4RE Leather

Thats exactly what the tyre Bible says. However they have ordered the tyres and swear it will be OK. I am really starting to loose it big time because what one would think would be an easy task has turned out to be a troublesome nightmare.

Does this mean that if it does it again when I put the 275/40/18 on the frear and the oem rear 245/45/18 on the front It might throw another wobbly? And if it does instead or taking the rears off this time. Put the 225/45/18 oem back on the front! I am now officially on Prozac and class 1 pain killers as my brain just fryed!!!

1 wheel has minor kerb and is hardley noticable but the rest are excellent and like I said. One brand new (Not refurb) It may have got wet as it was lost in the South China seas for a few months:) Joke. I witness it's arrival from Japan and it is not a cheap item. The car is a early 2009 with 11300mls on the clock. And i wash my wheels in a mild solution of cleaner every week. However the tyres are bought and paid for and I have a supercharger to payfor so need to keep in a budget. Waiting for Abbey to come back with the shipping price but it's a £10k job Wheels will be about the only thing I will put on the outside. Under the bonnet and interior. umm well thats a different matter:) peter

http://www.carbibles.com/tyre_bible_pg4.html 275/40/18 on the rear will give a Difference in circumference of -1.5mm or - 0.07% So when your speedo reads 70mph, you're actually travelling at 69.95 With the 275/35/18 on the rear gave a Difference in circumference of -84.44mm or - 4.13% So when your speedo reads 70mph, you're actually travelling at 67.11. Blimey I am knackerd now!!!

I only put that link to Tyre Bible as it has a load of correct info for newbies like myself and gives it in laymans terms. I only described what happened when I put 275/35/18 on the back. I honestly thought the front was rubbing as i went into panic mode > but after a chill pill it had to be the rears if that slip light came on. I am beginning to think I should have bought that Ferrari 456 that i liked. but then i suppose I would be under the bonnet all the time and on a forum full of horay henry's instead of a bunch of rough necks like us ha ha:) Peter

They are what ever came out of the factory 18's with one brand spanking new front at tyre 245/45/18

What ever it came out of the factory with I hope. Plus 35 psi in the tyres:) I have a fat bugger of a mate that lowers the car considerably ha ha. It's all sorted now thanks. The rear OEM 245/45/18's that are on the rear will go back on the front as we tried them yesterday. Plus many many people on here do the same thing. Then 275/40/18 on the rear. A guy that works at tyre fitters who was not there yesterday has a 350z and runs the above combo on his 2007 GT with no probs at all. Peter

Should have said the only colour apart from the obvious that compliments a Silver car apart from those nice chrome ones is Black. How much were they as the look great. Wonder how much my rays are worth. I even have a brand new one with unused 225/45/18 Potenza so thats five all told. Trouble is with insurance companies they consider larger tyres or Chrome wheels as a mod. then they rub their hands together and proclaim that the wheels make it more knickable and want more dosh! Tell them you have no mods and they send their own assessor to check the car and he sees ya lubbly jubbly shiney's and the swine will berrate you with a barrarge of rules and word plays! The car God demands a sacrifice!! Peter

I only have the OEM 245 on the back at the moment so 275 will be a lot better for me. Plus due to a medical condition I am forced to visit at least one Hospital a week come rain or shine. And I am fortold that the RE050'S have excellent grip in the wet over the 040's! Funny how thing work out. My last car was a Nissan pathfinder Adventura. And the OEM were Bridgestone twin Dueler. I gave them away and put General Grabbers on. Silly really as the Duelers were new and £170 each so I should have charged him £200 mate or no mate! Peter

It does go on the manuel as i tried but they relocated the 4 way flasher button behind the gear lever and there is no hole cut out for it. From what I could understand from the lady is they need OEM parts to make a mold. I was not aware that the latest model's had a longer electric window and mirror panal? The carbon set you can see on ebay is about 3 inches short of covering it plus there is no cut out for the door pull and nothing seems to align up? It also has 2003- stamped on the box, which i did not know about until it arrived. Dont rush in and get that ugly stickon alloy thing. I have heard horror stories about them peeling in the sun and when you take them off the throw them in the rubbish, they pull the top layer of ya dash off with it! Peter

No problem but I have not got a clue. If you Google Tyre bible http://www.carbibles.com/tyre_bible_pg4.html (The calculator that a lot of tyre fitters use) then go to page 4 of 4 and down the bottom of the page is a calculator where you enter the fsize of the tyre you have on the rim and then entre the tyre you wish to put on the rim and it will calculate the plus and minus and tell you the real speed you are travelling when the speedo shows 70. For example with the OEM tyres the car will travel 70mph when the speedo shows 70. No plus or minus difference. A few examples then go try it yourselves. Make sure you use the tyre size calculator at the bottom of the page and not the offset one in the middle! If I change my rears from 245/45/18 to say 275/30/18 at a speedo reading of 70 you will have a minus % of -8.19 Which might be what I tried!. now enter 275/35/18 and you have a minus of -4.13. and lastly because you can all play with this until your hearts content. enter 275/40/18 = 0.07% at 70mph = 69.95 mph and thats as good as dam it. Please all you old sweats remember i am not a tyre man I thought I knew a lot yesterday morning and when I went to bed I realised i knew nothing. Mind you even the tyre guys were puzzled and we send Ferraris their all the time, hence the trust. Got to shoot as this is taking up to much of my time. The only people who know the answeres to your questions are the ones who have the same car as you and have worn the T_Shirt. Not me as I have a 2009 that i have owned for a few weeks and am a jinx:)

I Turned the traction control off. Think something got missed in the thread. I lost all drive as the car went into fail safe? As soon as I put the 245/45/18 back on it was fine. To reiterate I put the rear on the front (245/45/18) and the RE050's on the rear. It was the aspect ratio that caused the problem Inadvertantly 275/35/18 which if you were to enter into the calculator on page 4 of the Tyre Bible you will see it makes the car 6mph out! However 275/40/18 is the correct tyre which I had all the calculations from the yanky 350z forum and I know someone running this combo which if fine. Anyone who wants to witness what the effect this wrong combination has on my car is more than welcome to come along to RSR in Croydon (who i trust infatically) and I am sure if you pay them they will put the wrong combo on and I won't even reach the top of the lane. We spoke direct to Bridgestone and Nissan technical department this very morning. It's the old senario that if you put 10 people in a room for 5 mins then get them to write an independant description on the last 5 mins you would get 10 different answeres. A good example was the carbon fibre interior kit i got yesterday. The description said 350 zed new carbon interior kit. When I got it I found it did not fit? Thats because I have a 2009 350 and this was a pre face lift kit. Know one thought to check because we tend to give advice about car or product that we own and no thought is spared to the question. "What do they own"? The person who is at fault here is myself because l asked for the wrong tyre and thats what I got. All I know is it refused to soldier and the combination of £500 on tyres and £335 on the carbon kit both of which had to be sent back made for a very wasted day. As usual guys, thanks for your imput, and I am sure the way out of this is to drive backwards off Beachy Head sticking my head in the clouds as I fall. Knowing my luck l would survive. Regards Peter

The rays are gleaming and unmarked and compliment the car which is silver. And it seems pointless paying out for wheels when I like the ones I have. I am using RSR in Croydon and am happy with them, and 4 new bridgestone re050's the sizes i want will not be far short of a grand. The main reason I want more rubber apart from the fact I hate spacers is thus far I have a Milltec cat-back exhaust plus de-cats and up-rev from Abbey. In addition I am getting a supercharger in a couple of weeks. So I just need some grip for the wet winter. Not that I am going to race away from lights or the like. I also want to keep the car Stealth. However black is about the only colour wheel that looks good on a silver car. Only problem the tyre company seems to have is a limitation on the ability to get different makes. I was considering Toyo Proxes as I hear they have good grip in the wet. Plus they are fair bit cheaper that the bridgestones. Something I won't do is compromise on safety. Mine or anyone elses as we all owe each other a duty of care. Thanks for your valuable input. Regards Peter

Hi folks Had a bit of a wasted day today and pi**ed off my local tyre company. I have a 2009 350Z with stock 18" rays and the standard 245/45/18 on the rear and 225/45/18 on the front. bridgestone pretenzas. Anyway i wanted some more rubber on the road and I have seen people put there 245/45/18 rears on the front and 275/35/18 on the rear or so I thought. Drove out of the tyre fitters with the combination as stated above and seemed fine round corners. But as i accelerated over 25 mph the yellow warning for slippery surface came up and the car refused to go over 28mph. It went into safe mode l suppose. At 1st l thought It was the fronts rubbing. Anyway we went back and it was obvious if i lost drive it had to be the rear. So we put the car back to stock and it was fine. We then went on Google and checked with tyre bible and found the problem. We should have put 275/40/18 on the rear and not 275/35/18. The tyre bible said that we were 6mph out. So I am going to change the lot for 255/40/18 on the front and 275/40/18 on the rear. That website is great for info. just put the sizes you have in the chart and hit the calculate button and it comes up with what the bigger size is and whats more it is correct:)

Hi I purchased this exact kit last week which arrived today. It is shiney and lookes terrific. However it will not fit a 2006-2009. but will fit earlier models. i have had to send it back. The door panels are 3" to short. The gearlever section does not have a cut out so the 4 way flasher button can poke through and the cross bit that seperates the CD from the radio is half the width it should be. Unfortunately they never thought to put it in the description. When l spoke to them a ice lady said to me that if we clubed together and got 6 owners of face lift models to confirm orders they would make a mold. Well gutted:(

I just have a lowly 2009 ZGT

I must have. But I might call it a day and try again another time before I beat me laptop to death with a frozen stick of rhubarb!

OK a cod then!!! But if you can l would appreciate it as it's kinda frustrating as i know it out there somewhere? Bet it's been put in the x-files unless you are the very chap him/herself!!

Hi looking for some help guys and I am not being lazy as I have trawled the ads for ages. Apparently there is a guy that make chrome gear nobs and break leavers. If some kind sole will give me the link to his page I would be obliged. Thanks Thenoname

Why thank you Mr Beavis kind Sir:)

Please excuse my ignorance, but what is a GT4 please?

abbey for sale. let's bid on it. umm I think you would have to drag Mark away kicking and screaming:)

As a PSV/LGV Driving Instructer and course tutor in transport studies I teach the art of scanning, looking at the foreground the near ground, both sides, behind and up above (where possible) The one question I always ask experienced driver's is what do they think they now do since passing their test. after a while someone will come up with the answer. it's the amount of risk they now take where b4 they wouldn't. ie pulling out sooner. not covering the brake at junctions and lights ect. and the faster your car the more risks we tend to take. And l am just as guilty. Thenoname

Familiarity certainly does breed contempt. I wonder how many of you got caught up in the M3 M25 right hook to Gatwick last Thursday morning. A Peugot van was doing approx 55mph round that corner which is blind, and ran straight into wall of traffic. The van ploughed into the back of a stationary vehicle and went airborne landing on the grass slope underneath the flyover. neither the van nor the car will legally be put back on the road.

That post by Dan was great. very interesting and full of logic. All I need now is to find the page that had the tyre size graph on it as l have been looking for an hour and i will be a happy chappy:) Cheers thenoname
