Im planning on getting 19's, but worried that tires are going to cost me too much, especially high performance onces. So whoever got 19's how much is your average cost for tires a year, do you swap tires 1/year? or just rotate 1/year?

Kimosabe

Well I hope you get a staggered set up if u do get 19s. And if so you can throw out the idea of rotating. And you have to remember, this car needs traction, even with VCD and LSD and TC it still needs good contact with the road regardless. So that said... you cant cheap out on tires. You will need good brand and ur looking to spend over 1k every time u change them up. How often, well thats all based on how much u drive... some say they need to every 12k miles.. others.. have lasted as long as 27k miles. You'll only find out by your own experience.

good question...
i switched to 19s at 15K miles on 6/15/05 T1S staggered

now, at 38K, they have about 1k tread left... 3/15/07

so almost two years, and about 17k miles, going to cost 900$ to replace all four..

so yearly cost would be 450$/year

thats not bad, do you do alot of hard driving, or is that daily driving i.e highway crusing or once in a while wot?

60% daily driving-> city/highway

20% - wot

20% - flying on surface streets

My first set of PS2s has lasted me about a year and I still have a lot of tread left. I'm guessing another year or more on them. That includes 4 HPDEs on them and a few autocrosses. Plus, it's my daily driver.

it all depends on ure driving style. i was on stock tires for 34K miles..... and i put on tanabe gf210s at 24k. tracked once too. but then again, i drove them until they were BALD.

most of that was highway miles, about 80%

Lots of factors here.

1. Are you dropped and have not corrected any camber issues? This would decrease life of tires.
2. Different tires have different tread wear ratings. Find a balance between tread wear rating and performance and that should help with life of tires.
3. How big do you wanna go? I run 285/35/19 in Rear and 255/35/19 Front. Some people run 275/35/19 F and 245/35/19 R. This will affect cost of tires.
4. Are you willing to unmount tires and have them swapped sides. Not rotated, just R moved to L and vice versa. If so then that will extend life of tires a little. High risk of damaging wheels though.

To answer your questions though. About 1G for a year and half, approximately 15-17K miles.

If a 17 inch tire has a wear rating of 300, and a 19 inch tire has a wear rating of 300, they are comparable.

can you explain (just curious)...

Because of the staggered setup, normal rotation is not possible. An alternative for some tires is to swap them side-to-side on the car. If the tires are directional, you must dismount and remount them on the other wheel. (For more info, check out this DIY thread... https://my350z.com/forum/brakes-and-suspension-diy/137762-how-to-rotate-staggered-directional-tires.html )


For those of us with high-dollar aftermarket wheels, there is nothing scarier than watching a tire-monkey mounting a tire on our wheels. The risk of getting them scratched or damaged is always present.

Hard to give a conclusive answer since mileage per year plays a huge part in this.

Yes it will. If I decide to keep my 19" D5R Speed Stars (might be up for sale) that's what I would like to run on instead of 245/35ZR/19 & 275/30ZR/19.

If your looking for performance/dollar give toyos some consideration. Bang for the buck, they are hard to beat. PM me for a quote.

i knew that... when u said dangerous in swapping was wondering what you meant.

A reputable tire shop friend (in business for 41 years) advised me to swap left & right fronts and said even though they were directional, it should not cause any problems. Ive done that for the last 3k miles and everything seems fine..

Kind of. But he asking about price of 19" tires per year and tread rating would affect that.

I say kind of because of this from Tire Rack Tire Tech.

Treadwear Grades

UTQG Treadwear Grades are based on actual road use in which the test tire is run in a vehicle convoy along with standardized Course Monitoring Tires. The vehicle repeatedly runs a prescribed 400-mile test loop in West Texas for a total of 7,200 miles. The vehicle can have its alignment set, air pressure checked and tires rotated every 800 miles. The test tire's and the Monitoring Tire's wear are measured during and at the conclusion of the test. The tire manufacturers then assign a Treadwear Grade based on the observed wear rates. The Course Monitoring Tire is assigned a grade and the test tire receives a grade indicating its relative treadwear. A grade of 100 would indicate that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.

The problem with UTQG Treadwear Grades is that they are open to some interpretation on the part of the tire manufacturer because they are assigned after the tire has only experienced a little treadwear as it runs the 7,200 miles. This means that the tire manufacturers need to extrapolate their raw wear data when they are assigning Treadwear Grades, and that their grades can to some extent reflect how conservative or optimistic their marketing department is. Typically, comparing the Treadwear Grades of tire lines within a single brand is somewhat helpful, while attempting to compare the grades between different brands is not as helpful.

If you want the best thread life get the Nitto 555.
However, you'll have to deal with sub-par dry traction and ABSOLUTELY HORRIBLE wet traction.
