Those will not rub at all with a correct offset. Remember there is no 245/30/20 tire that i know of that has correct weight index. All of them are 90w. You need at least 92 in front. I am running 275/30/20 in the rear and 255/30/20 in front with no rubbing issues. You can see it in my post on this page. GL!

Yea I've looked at ur post prior to posting. But I really like 245 cause it shows more of a difference between front n back on wide

I'm I gonna need spacers?
How much do weight speed index matter?
No rubbing on 255 even on turning corners?

As for spacers there is not an easy answer. You ned to messure the gap between tire and a fender it will determine the correct size. Nothing less than 10mm is recomended as those are hubcentric spacers. Weight index actally matters a lot since the tire's inner wire will not be able to hold through heavy forces generated by heavy car. Tire may just blow at speed.

Sorry for this noob question- what does offset mean??

toyota2bmw

Offset is the distance between the wheel hub and how far the out rim wheel will poke out to the fender. The more +offset you have, the close it's going to get to the fender. I have 20x10.5 wheels in the rear with 285/30/20 with an offset of 22mm and it does not rub at all. I am lowered with coil overs too.

By any chance you rub with the tire/wheel settings you get, no worries. Call Tony Saggu to roll and shave fenders and lining and you will be good to go. Check out my posting below:

Question .
I have Vossen rims with 255x30x20 front and 285x25x20 rear looks great but was wondering if i can run 255x35x20 front and 285x30x20 rear with out problems to have more sidewall -Rear fenders are rolled
front might be a problem?

i use 245 30 20 285 25 20 lowered o coilovers. tire is just on the fender line. rides hard because of 30/25 side walls. opt for more meat on the tire maybe going skinner with a lil stretch will allow u to not rub

inktoxicated

so i put new tires on. 245 35 20 ventus evo up front 285 30 20 evo in back. wow the softness is night and day to 25 seires sidewall. but the thicker sidewalls raised me a lil and canceled out fender room. i was running 10mm spacers on my vossens. so 20x 9 with 10mm spacer 20x 10.5 with 10mm spacer. was rubbing the paint right off the fenders. pretty much undrivable. had fenders rolled and it still wouldnt cut it. it was just to wide with those tires. so i took spacers off and dropped it back down about an inch. the fender roll still comes in handy without the spacers.
