285/35 or 305/35 with sportlines

I am planning on getting 20x8.5/10 wheels for my car but was wondering with how aggressive the sportline drop is if a 305 width tire on a 10 wide wheel would cause some rubbing problems. I know 285 should be fine but I will take more rubber on the ground if i can.

May just depend on offset.
You should ask this guy, who is on this forum.

I believe he has 305/30/20 now.

I was told by a couple places not to go 305. I actually have 295 30 20 in the rear

Ya the offset I would have is +45 so 305 might be pushing it

305/35/20 with the tire tucking with a 20x10 with +45 offset if this helps any. Also lowered maybe a good 2.5"+ or so

No rubbing over bumps?

Although I had the OE GT500 wheels which are around .55 offset I ran the stock 285/35/20's and with the Sportlines I could have gone to a 295/35/20 but not any more.

Yeah, 55mm offset is pretty high, pushing the tire inboard. I'll bet a 45 offset would allow a wider setup.
A 10mm difference in offset would equate to about a difference of 20mm in tire width.

BTW...305/35 seems to pushing it a bit for a 10" although it obviously works for The_Chech.
Also noticed makes for a 28.4" dia tire, which is taller then most.

It seem like 285 or 295 is the way to go if I want to play it safe. Anything is better than the 245 P-Zero's on there now.

With these wheels I could have added another 1-1/2" making them 11" wide without impacting anything except relocating the sway bar. I had planned on adding 2" on my TrakPak wheels which had an offset of 48mm...they still would have cleared although 19 tires are somewhat limited in anything bigger than 285's.

I just bought 20 X 10 Niche Lucerne Black Chrome rims () with a 40 mm offset for the rear.
I plan on using 295 35's.
Any thoughts on potential clearance issues would be greatly appreciated!

I only had slight rubbing when hitting a huge pot hole or the car goes down a big hill under high speed causing the car to squat really hard. It never did any thing to the tire or fender well. You could hardly tell the tire even made contact in side the fender.
