go check at a tyre shop, I'm pretty sure 225s are the max u can run on a 7" wide rim. 7.5" wide and u can run 235s legally. I had this problem when i bought some 2nd hand 235s for my 17x7 and tyre shop said max I could go was 225.

It would be great if someone with the knowledge could post max recomended widths for each rim size. Im not talking about the max that will fit im talking in regard to the widest you can go before handling is hampered.

I dont have any idea what the actual widths should be but something like this

7 = 225?

7.5 = 235?

8 = 245?

8.5 = 255?

9 = 265?

9.5 = 275?

10 = 285?

10.5 = 295?

cheers

i know you can go 245's on a 8" rim. i have 225's on my stock r33 rims and the sidewalls are on a bit of an angle. i think 235's would be pushing it.

what are the rims off? 18x7 sounds like the size of a wrx wheel. in which case they have a different stud pattern to skylines. they are only 5x100, not 5x114.

What stud pattern doesn't have any relevance to what tyre u can run on a wheel.

Use this calculator. It will tell you the range of widths a particular profile tyre can go on.

i know pattern doesn't have relevence to what tyres you can run, but it does have relevence to whether the rim fits on the car. was just making sure that he wasn't buying rims that wouldn't fit.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
