Looking to upgrade the stock 18's to either 19s or 20s on my GT. From what I've researched, it seems that 19 inch tires are generally more expensive than 20s due to the variety of 20 inch tires that are manufactured.

From a total cost standpoint, in the long term, would it be more cost effective to go with a set of 20s due to the lower cost of tires, or is the difference in price between the sizes marginal?

I think 19s look the best on s197s but would bend if the price of replacing tires on 20s is more cost effective.

I think 19's have come down now in price also so it may be a wash. I hear the Hankook's are a good deal.

I have 20's on mine and love them. Many will say 20's are too big on a Mustang, but the newer 2010+ has a more bulbous rear end and 20's look proportional.

I get people all the time saying "those are 20's?"

20" wheels will always be more expensive the 19's.. there is more material, thus a higher cost....not a ton higher but 30-50 per wheel, times that by 4 and your a couple hundred more...20" tend to have more tire choices, not a lot but some and the tires might be a tad cheaper in some regards...but the exact same tire made by the same company will be cheaper in a 19" then a 20", again more material higher cost...now there are always exceprions to the rule, but this will usually be the case.

I just put 275/40-R19 Sumitomo HTRIIIs on all four corners after much debate. American Muscle had the best price. I prefer the 19" wheel for the additional sidewall (needed for Houston streets). According to Tire Rack's testing, the Sumitomo beat the Hankook (my second choice). It seems the Hankooks are a little stickier, but the Sumitomo is a bit more predictable with a stiffer sidewall. I found the 275/40 to be the best bang for the buck because you can run it on all four sides and there seems to be more of a price jump with the 285/35. It's also the same diameter as the factory GT Premium 19" tire (245/45/19).

Hope that helps.

thanks for the responses guys.

You can't really go wrong with either.

I think they both look great and for cost, it's very close. It really depends on how big a tire you want to run. If you stuck to a 9" wide wheel and went with a 255 tire, the prices will almost be dead-even.

Are there any wheels you have in mind?

I would stick with 19's. They've become a lot more popular and the cost of tires has come down substantially compared to when they were less common (earlier 2000's). Plus, IMO they look much better than 20's on Mustangs.

Good luck with your decision!

From a total cost standpoint, in the long term, wouldn't it be more cost effective to stay with the 18's that are already on your car? LOL I keep looking at changing to a wider 19 and maybe keep the stock for future winter tires.

Hah yes, but these janky 18's have got to go. I think based on everyone's input I will be going 19's. I like the Nurburgring wheels due to their light weight, but the AMR's are definitely cheaper. Decisions, decisions...

If performance means something to you, compare the rolling diameter of the wheels with tires. An increase in rolling diameter over what your Mustang has now will reduce its forward acceleration.

To the contrary, if the tire you choose has a better coefficient of friction with the road, you will be able to launch at a higher RPM and accelerate faster.

Wheels with a larger rolling diameter will also reduce lateral acceleration as the roll center of your Mustang will be slightly higher.

Larger diameter wheels with the same rolling diameter will have less tall tire sidewalls which affects the ride negatively, but is likely better for lateral acceleration.

The bottom line is, what you ultimately choose for larger diameter wheels and tires is a tradeoff. Think about it, and ask questions from Mustang folks who have done it.
