How long do your tires last?

[Shadow277]

I am new to the rear wheel drive lay out. I heard the rear will always burn through tires faster than the front. So yes, my question is "how long do tires last you?" I am hoping you guys will have fun comparing tires and their endurance. It should be helpful in this community. I think this format will help:

What type of driving do you mostly do?
Tire brand and size:
Duration in months:
Duration in miles:

So for myself I would have to go with this for 2019:

What type of driving do you mostly do?
Commuting with occasional canyon driving.
Tire brand and size: Toyo Proxes T1R (255/35 and 305/30).
Duration in months: 10
Duration in miles: 6,000 miles

Fronts could have gone another 6,000 miles, but from you all advised, 20" Niche wheels are too heavy for road course work. Stylish? Yes. Functional? Not so much. I recently bought 2019 Premium wheels used and now have Firehawk Indy 500s. If anyone is interested, I will log my experience and see how much of a difference there is.

Daily driving and road trips with lots of highway pulls, hard accel with 700-800whp.
Michelin Pilot Super Sport 305/35/19 and 285/35/19 Staggered
Roughly 6-7 months (rear)
20k+ miles

My rear MPSS lasted 22k with the belts showing through, so I'd say 20k realistically. That's on a staggered setup with no rotations, and alot of hard accel. They impressed me. The fronts I'm still using, I've lost track of mileage but I'd say over 30k and they still have plenty of tread. I expect 40k out of them.

 

[SAY WHAT]

Summer set:
Michelin PS4S
255/40/19
285/35/19
9 months of use (16 months old) 13,000 so far.
daily commutes and road trips most 70% street 30% highways including road trips

Winter set:
michelin x ice 3
235/50/18 (factory wheels)
8800 miles
9 months of use (33 months old)
Mostly used when i head up to Michigan and when it drops down to 35 at night.

all season sets
pirelli p zero
235/50/18 original stock set
believe it or not they lasted me about 28k miles with some tread left. ( pretty much drove like a grandma most of the time) until i hydroplaned a bit and then i smoked them for the winter set.

2nd stock set up bought used wheels and tires for $500
pirelli p zero
235/50/18
about 5500 miles on them mostly used between Nov-april if i don't go to Michigan

NEW all season incoming and track wheels set up

apex ec7 18x10 wheels

Michelin all season 4 275/40/18 on order. I cant wait to see how these compare to the all season 3+

re71 or ADVAN A052 tire for the track, i haven't decided yet.

I keep pretty detailed logs, so I'll play along:

Stock Pirelli PZeros lasted 6,680 miles (w/ some track time and autox in there) - corded middle of the rear tires at the track - too much pressure.
Street set #1 - MPSS (285/35R19) lasted 19,635 (street only) - corded inside edge
Street set #2 - MP4S lasted 15,611 (street only) - corded inside edge
Street set #3 - MP4S is up to 10,276 and still going

Track set #1 - RE71R 275/35R19 - 17 track sessions, 73 autox runs, 4,829 street miles - daily drove on these for the first 3700 miles
Track set #2 - RE71R 285/35R19 - 6 track sessions, 122 autox runs, 2,698 street miles
Track set #3 - RE71R 285/35R19 - 7 track sessions, 41 autox runs, 586 street miles - lost the left front tire due to a small chunk that unwound the whole tire.
Track set #4 - RE71R 285/35R19 - 18 track sessions, 48 autox runs, 964 street miles - reused some spares from the last set to get a bit more life from this set.
Track set #5 - RE71R 285/35R19 - 5 track sessions, 57 autox runs, 1,622 street miles
Track set #6 - RE71R 305/30R19 - 7 track sessions, 88 autox runs, 2,060 street miles
Track set #7 - RE71R 305/30R19 - 0 track sessions, 10 autox runs, 400 street miles.. and still going.

Just curious, what is your alignment like for your street set up? Is it the same as your track set up?

 

[Shadow277]

What tire pressure do you like it at? As in, how low do you go? Mine sits at 37psi.

I run the same settings street/track, and they're perfect for neither situation, but I get by.

For most of the life of the car it was 2.3 front camber, 0 toe, 1.6 rear camber, slight rear toe in, which wasn't enough to save the shoulders of wide track tires pinched on narrow stock wheels.

Now that I have camber plates and tires better supported by appropriately wide wheels, I'm running 2.7 front camber, 1.9 rear camber, and same toe settings as before. Track tire wear is improved with more camber and is 'good enough' for me, but its not as good as it could get if I ran even more (i.e. 3+ degrees), but I'm already losing street tires early due to inside edge wear, so this is kind of the middle ground for balancing street/track tire life for me. I'm not inclined to change alignments at home before/after events, so I'll just deal with getting 75% of the life of what the street tires could give.

I see, thanks for the insight. I see my self in a similar situation very soon. I still haven't decided on a track tire.
I also can't be bothered to have an alignment done before and after a track event.

Cold around 30-32. By the time they warm up its around 33-36, it really depends on how hot its out and how hard I push the tires.

 

[Shadow277]

Is that a hot or cold pressure? Mine don't go above 36 hot.

37psi hot on these roads easily being over 116F as 116 is the weather here.

shoot for 2.2deg front and 1.5deg rear then I guess.

I was going to pile in on the snark end of the spectrum to say "they last as long as it takes to save up for the next set".

 

[Shadow277]

Gotcha, I actually melt at that temperature.

So is 30psi ideal then for better grip? Does the TMPS go off below 30?

So is 30psi ideal then for better grip? Does the TMPS go off below 30?

Ideal pressures for grip vary. For tires with soft sidewalls, or perhaps tires not well supported by wide wheels - you might need a bit more pressure.

For wider tires on suitable wide wheels you might be able to run a bit less pressure. As a general rule of thumb, keep them <=36 (not pressures) for most street tires. I haven't seen one yet that likes >=37+ PSI hot

MP4S want to be in that 34-36 range when hot (which means you're starting many psi below that for your cold pressures). 285 RE71Rs on stock PP1 wheels seemed to like 33-34psi hot IMHO but opinions on that topic vary. For these 305 RE71Rs on 11" wheels, they can be run at lower pressures - like 31psi hot.

The best way to figure out the right pressures is to experiment yourself. Start by looking at your tire wear, and increase pressures if you're getting too much sidewall rollover (i.e. scrub marks past the little molded indicators on the tire shoulders), and decrease pressure if you feel that grip is falling off too much when pressures and heat builds up. A laser thermometer or tread thermometer is a good tool to check how the tire is heating and adjust pressures to even it out (less pressure if the center of the tire is the hottest part, more pressure if the shoulders are hotter than the center)

 

[Shadow277]

TPMS doesn't go off until the mid-low 20's. I'd have to test it to get the exact number.

I'm on 255/40 Fire Hawk Indy 500s squared (19x9 front and 19x9.5 rear [stock premium wheels]). I think I'll try 32psi in the front and 30psi in the rear to encourage more grip in the rear over the front.
Funny thing is that I feel steering is more responsive (crisp?) and more dialed in over my previous set up: 255/35 and 305/30 Proxes T1R on heavy 20 inch Niche Rims.

 

[shogun32]

I think I'll try 32psi in the front and 30psi in the rear

the rear tires do just one kind of flexing for the most part and carry MUCH less weight. The fronts are the ones that really suffer and benefit from more internal support.
