People keep the OEM sizes as thats what Nissan fit and it keeps the speedo correct. The car does not give a fig what size tyres you are running, what it cares about is the relation of the radius of the front wheel when compared to the rear. If you keep that relationship as it expects then the TCS will be happy, stray from its programmed size and it will have a fit. Many people fail to comprehand the relationship between wheel size (diameter of tyre), width and profile. All of them affect the radius of the tyre. So saying "fit a 40 profile and you'll be fine" is not right unless you specify the right width for the given diameter (in this case 18"). The problem many fall for is they fit tyres with the same radius front and rear. Then the car thinks the rear wheel is spinning faster than it is all the time, so TCS kicks in. The rear tyres radius needs to remain larger than the front so the car thinks they are spinning at the same speed. You could fit 15's if you wanted so long as the relationship front to rear remains (forgetting they wont fit over the brakes)

No, for every 100 it reads on the clock you will have done ~96, so at 1000 miles, you'll have really done 960

Think it made my speedo over-read by a couple of MPH. Between 245/45/18 and 245/40/18 there is a 25mm difference, or ~3.7%

Looking at this logically, I can see what they were trying to compare. Historically, the performance of the Zed could not be matched by an off the shelf hot hatch. They wanted to see if this "new" one could give better performance. And around the wet track it did, so it won. Lest not forget the 370z is a GT car and a damn quick one at that. I would and have happily drive it across the continent, no way you'd do that in your souped up Renault. So yes the Renault is quicker in the wet but the Zed has a lot more to offer. One interesting point they made which I agreed on is the Zed has a tendancy to understeer quite a bit before getting into oversteer mode. I'm sure this is for safety reasons and a good alignment could sort it out, but I think it does let the car down a bit. Also, as they didnt give it to the Zed, it means other numpties watching Fifth Gear wont be running out to buy one so we can keep it a bit rarer

Running 245/45/18 and 235/40/18 on the front no problems whats so ever. Ive done more than 20k miles on them too. Im replacing them for 225/40/18s as they are a hell of a lot cheaper. I personally havent found any of this traction control problems alot of people bang on about. Maybe my car is different? Clearly you've never understoon any of the posts I've made explaining how TC works then? You are not finding any problem as your difference in percentage terms of rolling radius front to rear keeps the stagger that the TCS expects. Should you run tyres with the same rolling radius front to rear you will understand what we are talking about. As for the OPs original question, yes you can run a 40 profile. I did on my 18s on the 350z as Falkens have somewhat soggy sidewalls and I was recommended to do so. You need to keep the OEM front to rear stagger in rolling radius though. So use 40 profile all round and you'll be fine AFAIK, but keep to staggered widths such as 225F and 245R.

Blimey mate! That looks like a bit of a mission - and more worringly looks like you werent the only ones to have that idea! To give the others an idea of what its meant to look like - switchbacks (looking other way)

Wow, thats pretty impressive. Hope its been designed for the 14v that may be delivered through the cig lighter though Import perhaps? They only have the rear one IIRC. Should have got a UK car

When I got my 18" Rotas from BigPhil he stepped down the profile from the standard to get around this. Seemed to work well for me, never had any complaints. Think I was running 40 profile rather than 45 profile. Obvoiusly the speedo was overreading, but thats no bad thing sometimes!

Pff you could get the Zed up there Mr AK One day we'll move up there with you and I can come out to play on days like these

That was when I got my 350z. No way I'd have an S2k over the 370z, 2 completely different cars, 370z has waaaaay more torque, especially with UpRev. Way more GT car though, so I expect the handling on the S2k is more nimble.

Seems to be working

Yeah easily solved if you have a missus who you can get to have one. Then you can "test drive" it now and again to make sure its running properly I was tempted to get one instead of the Zed, but knowing it had to be a daily driver of 70 miles a day, the S2k was just too much and would have driven me nuts.

Do you do delivery?

Sorry that doesn't qualify, so you don't need to be mean to it, and call it a shed. She's a daily driver. OK She did have some rust btw - on the discs after I'd washed her

But beware, not all chunky grips are the same. Consider the compound also. Some chunky soled boots I have are a nightmare in the cold dry conitions. My hiking boots are designed to work at such operating temperatures and so grip very well.

Google images would confirm you are correct sir - its a Blitz Sonic Power (which it appears is rather expensive!) It should say so around the inner rim of the opening (cant really see it in the pic, but the writing looks to be there)

We had roughly 5mm of snow on the Alfa this morning. Much nicer to clear than the frost

The Viper had a carbon shroud Rich so its not one of them. Looks generic to me

Panda time surely? Go see what its like up Scarfell

+1 I think we have been here before Chris iirc Indeedy - you pointed me in that direction

We had quite good success with Ontrack EasyRecovery on the missus brothers HDD when it was corrupted. Give me a shout if you want the details

There was a group buy thread where I think both were listed. Lets see if we can find it... Ah here we go - http://www.350z-uk.com/forum/viewtopic.php?f=33&t=32418

Can of worms this one. Cant remeber the sizes, but there are at least 2 different sizes on the Zed.

Bit mean to call the Giulietta a shed, but she is our run around car, and a great one at that

Nutters. Dont know whether its or
