Tire Size Recommendation!
 

My buddy owns an frs and bought 18x9.5+35 rims. He is lowered about 2.2-2.5 inches on bc extreme lows. Anyone have a recommended tire size?

To each his own. There is no one-size fits all. Some go wider & lower profile, some even for smaller 16" and stock-ish thread widths/sizes. Some care about flushiness with fenders and play with spacers & offset, some care more about scrub radius & bearing longitivity and leave as is. If it's for him, not for you (and just mentioning him as example), he should install whatever he prefers/wishes more. Be it some narrower stretched tire, be it some wider one, be it whatever is closer to stock diameter to not throw off speedo readings much.

245/35/18

That low, with that amount of poke, he'll likely need camber (lots) or stretched tires (<245) or both to avoid rubbing. Just my 2 cents

Im maxed out (isc coilovers) on 18x9.5 et38 with 225/40's. No rubbing at all untill i put 20mm spacers on the back for better fitment and now i rub a little but thats only in the back
Bottom line is he wont rub on 225's with no spacers

245 Front and 255-265 rear, but I don't know if they will fit.

Attachment 10882418x9.5 +34 w/ 235/40 nankangs. Very minimal rubbing in the front under full lock. Natural camber in the rear and about -2 in front on the camber plates.

Dang, sorry for that crap picture. Tapatalk mucked it up
