Hayd350 Posted October 17, 2017 Share Posted October 17, 2017 Morning chaps, Basically running a 275 / 40/18 on my 10.5 rim which i'd assume are pretty standard for uk 350z owners. Ideally for fitment I'd rather run a 285 / 40 however it seems to exist only in a run flat so it's a none starter. My question is in anyone's experience with tyres is there a brand that typically run wider which would give me that slightly taller side wall on their 275 when compared to say Falken's 275. Extremely reluctant to drop to a 35 profile on an 18 too. Any help is as always appreciated. Quote Link to comment Share on other sites More sharing options...
Ekona Posted October 17, 2017 Share Posted October 17, 2017 Short answer is no. Some may appear to sit wider due to the increased rim protection (Michelin especially have HUGE ones), but that won't give you a bigger sidewall as that will still be calculated from the 275mm width. What size are you running on the front? Quote Link to comment Share on other sites More sharing options...

What size are you running on the front? Cheers Ekona , I was hoping you'd chime in on this one. I'm running a 255 / 40 upfront on a 9.5. I appreciate the fronts will need to change if i change the backs but it looks like I'll be sticking with the more conventional format after your comment. To be fair there's certainly nothing wrong with it, the wall just tapers off a tad too early and in a readily available world I'd opt for a 285 / 265 set up.

Ekona Posted October 17, 2017 Share Posted October 17, 2017 Interestingly you've gained 12mm sidewall at the front using that combo, whilst losing a gnat's **** at the rear. I agree that going to a 275/35 on the rear would look a little odd, however if you dropped to a 245/35 at the front then went 275/35 at the rear you'd find them looking much better with just a 10mm difference between them. 245 is within spec for a 9.5 wheel (just!), so maybe another option?

Ahhh really, i thought I'd gain circa 12mm on the rear side wall too with a 285 / 40. (although i listed the 285 first, it was meant for the rear) I'll look a little more closely at a 35 profile before completely dismissing it. The main aim is to increase side wall height thus reducing the appearance of arch gap but keeping everything within spec. Form and function.

Ekona Posted October 17, 2017 Share Posted October 17, 2017 If you reduce sidewall, you reduce arch gap We are talking fractions here: I'm not convinced that a 285/40 would look noticeably different from a 275/35 if I'm honest, not from the side. 10/12/15mm is nothing, bearing in mind that's over the diameter so just 5/6/7.5mm top or bottom. On a car that's 4m long and 1.3m high it's going to be almost impossible to tell. I'd be more concerned about buying decent tyres than worrying about the width of a pen in arch gap. The guys that run 19s have got it right in terms of looks, but I prefer to stick with 18s as well because I don't want the extra weight.

Agreed, tyre selection is the more important thing here so it'll be the key factor in my decision making. To be perfectly honest trying to straighten the tyre wall and reduce the arch gap by the width of a pen is exactly my aim I'm in search of perfection and perfection is 4mil.

docwra Posted October 17, 2017 Share Posted October 17, 2017 FWIW the XL spec MPSS rub slightly on one of my arches where normal ones dont, youre probably talking about 1-2 mm at most though. Quote Link to comment Share on other sites More sharing options...

Hayd350 Posted October 17, 2017 Author Share Posted October 17, 2017 Cheers guys. Ill check out super sports, reviews seem good even if they are the same width they may be a better option over my Falkens. Think the Maxxis are best left for my pedal powered weapon though Quote Link to comment Share on other sites More sharing options...
