    I have been running the Michelin TB 15‘s on my RSR clone. I have them mounted on 15 x 9 front and 15 x 11 rear. They are great tires, seem to wear well and still pretty sticky on their third season.

    On my 15x9 and 15x11 Fuchs, I just recently installed a set of Pirelli Cinturato P7's in sizes 225/50VR15 (front) and 285/40VR15 (rear).
    The tires fit the wheels perfectly, have immense grip (if you want that?) and fit in the wheel arches fine (mine are turbo).
    Purchased them from Lucas Tire.
    The rears are expensive as you'd guess.

    interesting that your front tire size is the same size used on a 8" wheel. Do you think you could have gone bigger?

    The car looks right and drives well with this combination.

    I have Michelin TB5 R on my RSR-clone. 18/60/15 in front and 26/61/15 on the rear.

    Front size is perfect and the steering wheel is already hard enough not to think for bigger tires…

    For the rear, I saw the 2.8 RSR «Grand Bazar» with 29/60/15 size. For circuit it could match, but on the road, I'm pretty sure the tires touch the wings !
