Well for those with aftermarket wheels, can you tell a difference between 18x8's and 18x8.5's as in ride quality?? I have my perceptions I just want to know what yours is.<p><BR><BR>

A lower sidewall and wider tire is also more prone to tramelling than a thinner, thicker sidewalled tire. I don't know whether a 1/2" would make a noticeable difference but it's still worth noting.<p>-Eric
I went from 8.5 to 8" last week. I noticed a HUGE difference. The trailing that the tire did with 8.5" was quite noticeable and the ride was a bit hasher. I am getting a little better gas mileage as well.(1-2mpg better)this week with the 8". With a wider wheel the weight is usually higher as well. The rolling weight of a wider wheel is a bit more (comparing the same wheel) thus you will have faster wear on the brakes and rotors as well. I think I read somewhere recently that every 1 pound you add to a wheels weight it equates to 10-12 lbs pounds of rolling weight.( I could be slightly off whith those #'s) But lets just say that the new wheel weighs 2 lbs more and the rolling weight would be 10 lbs more per pound per wheel per pound. That equates to 80 lbs of EXTRA rolling weight. I also have noticed that the 8.5" was more prone to hydroplaining. Where as the the 8" was less apt to hydroplain.I hopr this helps. Rick
Mash,<p>If you go with a substantially lighter wheel and lighten up your brake rotors you can go with a wider wheel and still see the benifits that you are seeing going to a thinner wheel even though you would be going to a wider wheel. There are more variables than simply the width of the wheel. Weight being a huge factor but the brakes could offset that.
So true. It is to bad that most of the wheels in ouR price range run 26-30 lbs. Now if you go wider and with a 600.00 plus wheel to save weight, that is what you are talking about. And I agree with that. The total difference between my new wheels is 1.2 lbs less than the 8.5". And I definately feel the difference. Stopping power, acceleration and ride is much better with my 8" wide wheels.
All I have to say is that I noticed a BIG difference in ride quality between a stock 18" peg and a Evolve H5. The H5 rode a LOT rougher and it's supposed to be lighter than a Peg. I guess it's because it's a wider wheel and it's pulling the tire.5 inches wider than normal.<p>By the way this was on the same tires. PS2's.
remember another way to save weight is to upgrade to a 2 piece brake. EST has some that are great. I haven't tried anyone elses but Viva has some as well as does Evolve. There ahs been some reports of defects of the evolve rotors though.<p>this will help neutralize a couple lbs. you may add by a wider wheel.
I did not notice a difference in the ride quality at all. I am saying that since the main arguement here is weight and as Mash said either you can just get a lighter wheel or make up the wieght on brake rotors.(or both)<p>If ride quality is a deal breaker then I would recomend 17's all day long and if weight is a deal breaker then expect to pay a premium for 18's(since you can shave more weight from the wheel than the rubber) and get some 2 piece lighter rotors. But, if you can justify the money that would be needed for a noticable difference then seats and a lighter battery should be addressed as well. <p>In summary, the wieght saved by brakes and wheels is really trivial if you are going to stop there and if Ride quality is the main concern then 17's are a fit.
