I have 255/35/19 all season eagle f1s for my enkei rp03 rims measuring 19x9.5 and I have worn out the two back tires. I personally don't think I go too fast in the car. Just have a little fun sometimes and since those tires were so expensive, I would have thought they would have lasted me a longer time but they didn't

now my question is what tires would one recommend for the rear of my 8 that would last me a while with a lot of tread and still have good performance?

 

Are you staggered? Is the wear on the inside?

 

Seems weird I have run 245/40 off brand tires for a year and they are great with no premature wear and i do slide her out from time to time and they have a couple autocrosses on them.

 

not yet but the outside of the tire is literally flat but it still hasn't gotten to the inside

 

If the outside of the tire is worn or your tires are otherwise worn unevenly then I would seriously look into an alignment as it sounds like you have excessive camber on those wheels.

19 inch wheels also are an odd size and tend to have VERY expensive tires. My tires in a 255/40/18 are easily $100 more in a 19 inch size.

Once you have an alignment I would do one or both of the following. First, get a non-directional tire. I've ran Nitto Invo's on my RX8 now for probably 25,000 miles and enjoyed the tires. The construction is a mix of a street and performance tire with a 260 or a 220 tread rating. They are non-directional so you can rotate them even on a staggered setup.

Honestly I wouldn't bother with a staggered setup. Yeah it tends to look cool but the handling or performance benefits, in my limited professional opinion, are unproved on the RX8 with the exception of higher HP vehicles. I run 255's on all 4 wheels and it works just fine. The hassle and added expense of staggered wheels doesn't net any real benefits other than bling.

And if you're only interested in looks then you shouldn't be buying expensive high performance tires anyway!

So, buy 4 tires of the same size that are non-directional for easy rotation. Then, get yourself a good alignment for the street and just rotate your wheels every other oil change. You'll get a lot more mileage (literally) out of them.

 

FWIW I run 255/35/19 front and back and have even tire wear. However I do rotate my tires a couple times a year. As flashwing stated, get your alignment checked.

 

If you are wearing down the outside of the tire you really need an alignment....usually the wear from too much camber will be on the inside..

Too little camber or a lot of toe out in the rear would wear the outside of the tires.....neither is ideal

 

Eagle F1 A/S dont like heat very much. I killed a set very quickly after 1 autocross event.

 

The Eagles are really soft (Goodyear's "280" is really almost 200).
If you have some toe-in in the rear (sounds like you do), the outer edge will heat up and go away.

 

Unless the rear has positive camber, then my experience has always been that regardless of toe in or out excess toe will cause inside wear

unless he jacked the ride height greater than OE or has a bent frame it's impossible to adjust positive camber in the rear

Interesting.
Toe-in on my car causes the outside of the tires to wear faster.

 

Yes, it's interesting to me too because my experience has been the opposite. The exception might be not running enough air pressure relative to camber setting, which will result in outer tread wear

The results can be different between street and racing too. Despite running rear camber on the minimum setting for Stock racing (-0.8 deg) I still had slightly more inside wear on the rear Hoosier tires.

Outside tire wear on both sides of the tires could indicate you didn't have the tires properly inflated either. Almost happened to me.

 

I have Dunlop Direzza's on mine because dunlops have always been long lasting for the money and good performance. I got my car used, no damage to the car,,had new original set of tires on it/dunlops..they wore out in 20k miles or less,,,at least the rears were done .... I bought the direzza's and now at 18k miles,,i have maybe another 5-10 k before I will have to get at least 2 more tires..My back ones keep wearing out. ... First rotary i've had that this is happening with,,usually with the 50/50 weight distribution i never have a problem.

Anyone else having issue with rear tire wear??

 

Stop having so much fun drifing and spinning the tires is another option.

 

i wish..i have an automatic, i have had my share of manual rotaries and just wanted to be lazy. That is why it puzzles me..why the backs are wearing out quicker than the fronts..usually with any car it's the other way around.

 

I am having major issues with tire wear on the center of the rear tires. I think someone aboved mentioned excess toe casuing inner wear? My ride is about 1 1/4" below OEM, but it was lowered years before this started happening.

 

wow my stock bridgetstones lasted me like 8 months lolbut i did canyon runs daily

 

To bring what everyone has said together -

A) Get a professional alignment. Most tire shops will be able to take care of this and prices range from $60-120

B) Check the air in all of your tires periodically. When cold (ie before driving) make sure psi is at 32. I carry a pressure monitor in my car at all times - they're cheap and can help you out a lot.

C) Buy undirectional tires and have them rotated every 7,500 or so. Both sides of your car have minute alignmet and weight differences and rotating causes all tires to wear the same. If you are staggered, rotate the rears with one another, as well as the fronts (hence not purchasing directional tires)

I believe inner and outer wear may be attributed by + camber. I'm sure team is running more aggressive camber thus toe in causing inner wear. Street camber might cause outer wear. Either way, the speed of the wear for OP definitely indicates a toe issue. I'm guessing 3 weeks is under 1000 miles?

edit: Just realized, 3 months, not weeks. Not as bad, but still far from good...

 

If you are drifting, good luck with 3 months. I bought my tires about 6 months ago and after 2 events and some practice runs, my tires had about 30% left. That 30% was about 1 month into owning the tires.

Now granted I do run a severe camber setup, which I already expected shorter tire wear, so that is why the tires went like they did.

 

i run goodyear eagle f1's.... the only way you're burning through tires that fast is because you're doing it wrong... not really too much more to say about this. everyone hit the major points like, tire pressure, alignment, and aggressive driving so if you want to see your tires last longer then change one or all three of these

... just my 2 cents.... now for a tire that may last longer, I think that the hankook tire is an awesome deal for the money, continental makes some great tires that should last as well. go on tirerack and read some of the reviews on tires (best place to start)

 

I just had Nexen N5000 245/40/r18s put on my '04 today. My pressure warning light started beeping on the way home. The tires still had 50 PSI!! I just lowered them to 37 PSI. Haven't driven it yet. I'll post again in a few days and let you know what my assessment is.

 

All season tires in general are softer then dedicated summer performance so they can accomodate wide swings in temperature and conditions. As MM cited these Eagles in particular are known to be quite soft.

I wear my outer treads with excess toe-in ("snowplow").

Alignment, regular rotation and proper air pressure as others have cited are also key to tread longevity.

I have to say my OEM Dunlop 8090's lasted a good long while (over 20k) and I probably could have run longer 'cept I wanted to try some Toyo T1R's. But then again mine are summer only.
