M45 Tire Size

My friend is ordering some Volk GT30s in 20x9.5 and 20x10.5 +37 on both rims. My question is what tire size should he get??

I was thinking 265or275/35/20(FRONT) 285/35/20(BACK).

This is for a 2007 M45 Sport

thanks in advance for your help guys.

bump sirs.... haha

what car

its a 2007 M45 sorry i thought i put it in there..

how low is the car?

those cars cn be kinda hard to fit aggresive wheels on... but as previously stated it is important to know how low the car will be

as of right now the car is at stock height, but hes not gonna dump the car just enough where there is a slight wheel gap.  I figure hes gonna have to roll his fenders just in case. I found out how much the fronts should be 275/30/20, but the back i was looking at 305/25/20s, but im not completley sure

too wide i think.. the widest i would go (different tire brands stretch differently and are narrower/wider) would be a 245 in the front and a 275/30 in the rear. you can see how a 235 275 looks on an 9.5 10.5 by clicking on "My car" below

Yeah, I would go with 245 in front and 275 in rear.

would a 35 or 30 work with the 245 and 275? also what tires do you suggest? i was thinking about the Falken Fk452s i could get some for 670 for all for in these sizes..

u can use a 30 series in front for clearance but u should use a 25 series in the rear. 452 runs wide . i use it but i plan on getting nankangs(too many bubbles) some people love them

alright thanks for all the input i think i got it down.
