Lightweight wheels or wide wheels
 
The wider you go the heavier your wheel and tire setup is going to be. I want to find a good middle ground between cornering grip and weight. I dont think I need a 265 tire on this car if my only plans are basic boltons.

I was thinking maybe a lightweight 17x7.5 with a grippy 225 tire. With a +25-+30 offset

Any suggestions??

Also, Does camber + stretch have any benefits to handling? I see a lot of drift guys use it. It cant just be for the look can it?

This car does not need 265 - not enough power. 225-235 is enough. With lightweight 7.5-8" wheels you will end up with the same or even lower total weight than stock.

RPf1's in 17x8 or 17x9 with 225-255's are lighter than stock I believe.

You don't want stretch. It's more just for looks and fitting wheels that aren't meant to fit.

Moetivegt86 10-22-2013 07:00 PM

The weight im saving with going with lets say 17x8 with a 225 tire, Justify the loss in grip if I went with 17x9 245.

I think 235 on 8" is top of what makes sense performance wise. Still can be done at the same weight as stock.

Get some super light wheels. Some of the best weight you can lose is unsprung weight. Additionally, I don't think you need the extra grip from a super wide tire; the car just doesn't have enough power to overwhelm then on dry pavement with grippy tires..

If by grip you include braking, you should up size one inch if you go wider. So 18x7.5 or 18x8. (track) If you wider the stock rim and keep the same rim size, the contact patch goes wider but becomes narrower w/o a +size.

For DD I'd be fine w/ 17x7 or 7.5 w/ 215 or 225 respectively and better compound. (street) Even try 16x7 if you don't do brake calipers or BBK. But honestly the tire choices don't make 16's that attractive as tire weight is the most important part of the wheel package's inertia. This is why I started by looking at tires first before wheels.

For all in one, I'd go 18x7.5. Actually you'll be limited by the rims in question so you'll find you'll need to determine between which rims and what sizes they come in.

You do realize that rim diameter doesn't change the contact patch... if the overall diameter of the tire is the same it doesn't matter what diameter the rim is.

17x8 +35 to +45 with a 225/45 sticky tire will be a ton more grip than stock and still very light. The offset you mentioned will poke a lot without running a bunch of camber.

Just to be clear, 17" tires can be just as heavy or heavier than lower profile 18" tires. But there are weight savings in the wheels, as detailed below. Same setup I'd referenced earlier is 2.2 lbs lighter in 17".

I went for lightweight 17"x8+42 WedsSport TC105N they weigh 14.9lbs and I went with BFGoodrich Rivals in 225/45/17 and those weigh 23lbs. Grip on this setup is amazing and I am very happy with them. Got the wheels from Vivid Racing (Thanks!) and the tires from Tirerack (Thanks!). Here is a picture I took today for you to see.

I have some 17x7 BBS RK's that weigh 16lbs that have 225's on them. About the same weight as stock wheels/tires due to heavy tires.

Sorry, yes that's correct. If you +size and can maintain the same identical diameter that is correct. Usually though a plus size rim will be mated to a -05 in aspect ration which tends to yield an increase in tire diameter which increases the patch front to rear. But yes, the tire's dimensions are what matters in actuality.
