I have been looking for R-compound track tires to put on my extra set of stock wheels, and narrowed it down to these choices:
- Yoko A032: grooved, a bit on the expensive side
- Toyo RA-1: grooved, too expensive and not available through tire rack
- All others: not available in the right sizes (205F, 245R)

From reading around on this forum I get that the tire of choice for autocrossers is the Kuhmo in 225F-245R, with a bigger front sway bar. It would be my preferred choice for the track, but I want to keep the suspension stock, with the right F/R tread width ratio. The Kumhos in 265/45R16 would work, only the rear wheel is 7.5" wide and the spec ask for a range of 8-10".

Any experience fitting the 265/45R16s on stock rear wheels?

The 245/45/16 V700 tires on my rear rim are actually larger than recommended for a 7.5" rim (according to my Tire Rack salesperson). I got them anyway. I'd be surprised if 265/45/16 tires would work well without excessive bowing due to the relatively narrow rim width.
