My Z is on stock suspension right now but I am planning on purchasing tein s tech springs. I came up on a great deal of rpf1's that came with used tires with plenty of life in them..18x9.5 +15 (245/35/18),18x10.5 +15 (245/40/18). My question is: Would these tire sizes rub on tein springs? Any suggestions on tire sizes that would fit better? Any pics with these size wheels on s techs would be appreciated..thanks

 

No it won't rub. Those tire sizes are all wrong.

 

Welcome. You intend to put 245 mm tire on a 10.5 inch wheel? OK cool.

 

What tire sizes for both front and rear would be the best?245/40 275/40? Those tires came on the wheels from the previous owner

 

I have S techs with the spring mount cut. Rpf1s the same sizes as yours and I'm running a 265 35 up front and a 295 35 rear. My fenders are rolled slighty in the rear but I think I wouldn't have rubbed even if I didn't roll them

 

03threefiftyz, what tire sizes would you suggest?...Ztouring04, when choosing what wheels I was going to buy I would always look for your z (which I found on google images) haha nice car!

 

265/35 and 285/35 would work.

 

Yup, just mount the current rear tires up front and buy the proper rear tires for now. The 265/35 285/35 combo would be great, but will be more expensive initially.
