Does anyone know if I'll have problems plus sizing the Spyder rear tires from 265 to 275? I'm currently on Bridgestones but really miss the stickiness of PS2s. For some reason PS2s are $100 more per tire in a 265 than a 275 and they dont make the new Pilot Super Sports in a 265... I know the rear wheels are wide enough to take a 275 but will I have issues with rubbing and/or change in outter diameter?

 

You will be fine

PSM might be a bit more sensitive since the sidewall ratio will be higher.

 

I am Running 295's on the rear of my 2007 Cayman no problems so 275 should be no problem as Championishop stated..

 

I've seen threads elsewhere that suggest oversizing the fronts to 245's if you are going to oversize the rears to 275's. Something about keeping the ratios the same.

 

hehe I was just going to ask about that. I've noticed a bit of understeer already and wouldn't want to exaggerate it any further.

 

Deffinately do what saeyedoc said 245 ,s in the front ,If you make the rears wider . When I first put my 295 on the rear it handled horribly until I went with the 245 on the front .

 

Running 245s in the front with 275s in rear is standard. That's what all the E46 M3 guys run.
