    max rear tires for 718s

    hi i recently got a set of new wheels. i got a good deal on some volk te37 ultras.
    the specs are

    Front 19×8.5 offset 52
    Rear 19×11 offset 53

    im trying to get a set of tires for autox. i was leaning towards a set of re71r. the problem is that the sizes for the rear are on 285/35/19 or 305/30/19. i was wondering if the 285 will be to stretched of should i go with the 305? will the 305 have clearance issues? for the front i was looking into 255. will going for 265 have better balance for the 305?

    thanks in advance

    I'd be more worried about the offset on the rear wheels than the tires, personally... ET53 seems potentially problematic knowing that ET40 with 11 inch wide rears just about fits. May require some decent sized spacers. 305/30 seems too small for me in terms of circumference, a full 4 percent less than stock. 285/35 is better and should not be a stretch on 11" though I suppose for AutoX it won't matter that much unless you would just be on the edge of needing another gear somewhere.

    You will need a minimum 10mm rear spacer to adequately clear the strut and rear toe link. I have ET50 and run a 7mm spacer. People have run 305 19 RE-71R on the rear.

    3mm is really tight. With factory rubber bushings, they can compress more that that if you hit a bump. But it all depends on where the tightest area is. Tire sidewall to strut is sensitive to tire air pressure. Lip of rim to toe link is sensitive to how much movement in rubber suspension parts. 7 - 8mm is generally considered the minimum safe clearance.

    I had 5mm from the rim lip to the toe link on OZ Ultralegerra 19x11 et 50 with 7mm spacers. (effective 43 mm offset) I changed to a Tarett rear link and got a couple more mm clearance and eventually went to 10mm spacers and now have a 'comfortable' 9mm clearance between the toe link and rim, but my 981 CS now has mostly monoball bushings, so parts are going to move less.
