this is unexpected news to me...What are we looking at for replacement tires as far as costs go? Tire wear is one big reason I bought a Rx-8 over an NSX as my every day driver. I guess 10k miles is better than 2k or 3k though
Originally posted by 6speed8 When it comes time to replace tires, I will most likely go with Toyo Proxes T1-S - had them on my previous car, they last a good 30k miles, are fantastic in the wet and are very quiet running.
Man, its hard to find 225/45/18s
The only brands I could find were:
Bridgestone (doh!), Michelin (he, expensive), Pirelli (same as Michelin) , Continental (I think I'll regret it) & Dunlop (yeah, great for Winter).
I wasn't able to find anything other that the brands mentioned above. And the last 2 are options for Winter tires. So I guess I will have to go with OEMs for the time being until I hear from someone who's gone in other direction for similar tires.

'04 RX-8 Touring V.Red - Gone!
I'd recommend 245/40/18's as replacements -- almost the exact same rolling diameter as the OEM size (about 0.2" difference), a little extra tread, and certainly no issues with clearances, either. They should fit just fine on the stock 8" wide wheels. To top it off, you'll have a much broader selection, and, hence lower prices...
The diameter of the tire is the distance from the rim to the outside of the plus the rim. In the case of the 18 inch wheel, it is 18 inches plus 2* either 245* 0.40/25.4 or 225*0.45/25.4. The 25.4 is a conversion factor to get from mm to inches.
In other words the distance from the rim to the road is the width of the tire times the aspect ratio.

What's your driving style oh yeah "but now i corner hard and step on the gas". No use moaning about tire wear if you're accellerating and cornering hard and not spinning off the road. If the tires weren't wearing, you'd probably be wearing a tree by now.
Complaining about tire wear is a little like buying a hi-brightness flashlight and complaining that it goes through batteries fast. You know, the whole cake and eat it too syndrome?
Luckily for me this is an issue that I no longer have to worry about. The dealer I bought the car from has a program whereas if you let them do the services and such I get free tires for the life of the car! Can't beat that with a stick! :D

On the other hand, many would argue that the RX-8 is supposed to be a high performance sports car that happens to comfortably seat 4 people. As such, it's equipped with high performance summer tires, and one of the defining characteristics of such a tire is that it doesn't last all that long.
Still - the tires should last somewhere in the 15K, maybe 20K mile range, depending on style (hard drivers could only get 12K miles, freeway cruisers might get 22K miles). I haven't seen a correlation between a 100 treadwear rating being equivalent to 20K mile life, and all of the 140 to 180 treadwear tires used in the Miata community never get anywhere near 20K miles. Most references will say that the treadwear ratings are relative only within a manufacturers line of tires, and NOT between tire manufacturers, which casts doubt on a standardised treadwear 100 = 20K miles factor.
There are all-season performance tires out there with treadwear ratings in the 300 range, but you'll definitely be giving up some dry grip and responsiveness to go to a higher mileage tire like that. The trade-off is performance vs. long life - you can't have both!
Life is too short to drive boring cars!
