I'm planning on runing either 275's or 285's out back on a 10.5" wide wheel. I know I'd have to roll my fenders to fit 285's, but what about 275's?...any modifications necessary?

 

depends on offset but usually no. for 285, u can run falken FK451, on a +23 offset wheel with no rolling

 

offset is +22 front and rear

 

You will barely clear. Depends how low you decide to lower the car also will make a difference. Lowering the car to about 1" gap will possibly make you clip the fenders on hard turns as I have been told.

This is with 275's.

 

Car will be lowered with Tanabe GF springs. Will 275's be too stretched for a 10.5" wheel?

 

you could be ok at a 22, but I am not familiar with the drop of the Tanabe.

It really depends on the tire....some 275's are as wide as 285's, while some are as narrow as 265's

 

If you dont mind rolling your fenders, just do it and be safe. I have 275's with a +23, one inch drop, and no proplems.

 

I would go with a 285. I have 10.5 wheel with 285 and it looks perfect. I went to a Z
Convention in O.C. and a lot of them had 275 they looked stretched. the ones that looked all right had Toyo's or nittos. What size wheels?

 

The rear wheels will be 10.5" with Michelin Pilot Sport PS2's. You guys think that tire will look stretched?

 

What size? 18, 19, 20. I have 20x8.5 front and 20x10. Yesterday my posting read that my rears were 10.5, but my bad-they're 10. Tires are BF G-force T/A KDW. 255/35/20 front 285/30/20 rear. I think that its goin to look stretched with 275. I also have a Nismo S-Tune Suspension and my Offset is +25 all Around. I did not have to roll the fenders it only rubs a little when taking real sharp turns.

 

The wheels are 19x9.5 in front and 19x10.5 in the rear
