How many runs do you have?
How many runs do you have? I just bought a pair of MT ET Streets. I am just curious how many runs and possibly miles you have on your tires. I am sure millage is low and I don't plan to run mine on the road aside from maybe a trip or two to the cruz next summer. I have heard of people getting 30 plus and still having plenty of tire left. Just curious. Thanks
Much of a burnout for each run? I know each night is different how the track is hooking but on average would you say you do much of a burnout? Also have you ever ran them on the street. If so did you have to heat them much for them to hook on the road?
I have a quite a few passes. I honestly want to say at least 100 passes if not more since ive put them on last year. Im at the track almost every weekend and usually make between 2 to 4 passes at the track every visit. Ill do a a pretty decent burnout till I see smoke in the mirror then roll out. I take my car out crusing pretty offten with the MT ET streets and have alittle over 5K street miles on the tires. And Im still cutting 1.5x 60's at the track.

When it comes to tire life, there are a few things to consider....
-Your power level and tire needs
-How many runs you do a year on average (most track days can net you 2-5 runs if not more)
-How many miles on the street your driving
-Storage of the tires? (do you have cold winters?)
Every tire is different and every driver is different so you will get some variation. At lower power levels where a ET street is more then enough, you can wear them to nothing and the compound can be hard and it doesn't care but a car that makes 500+ may go from hooking to spinning with in 50 passes.
I got a buddy running low 9's where his tires are considered shot, but stick them on a cam only car and it may still work great.
One big issue I see people having are
-Road Hazards
-Heat cycles
As apparent, any screws, debris, glass and things like that can damage a tire and given the nature of the tire, a plug may work but then your trying to burn it off and may re open the hole.
Also with heat cycles, the more you do, the harder the tire gets and may take more to get it back to the sticky tire it needs to be.
ET drags are even more effected by these conditions and thats why they are not considered to be driven on the street at all.
Personally a M/T ET Street DR is considered the optimal street tire, I would use ET streets if I needed a guarenteed hook for a street race and I would use it sparingly. I think a Bias ply should be track only but that is in my opinion.

Good lord, what size? I'm about ready for a new set!
I picked up a set of et streets with only ~25% tread left halfway through this season. Have ~20 passes and 100 street miles and they don't look any different than when I got them.

My last set I used til there was nothing left.. I think I got them to last 2 seasons. And drove around on the street a lot too. Probably drove to the track on them 2-3 times a week.. I dont know how many passes, 800? or more?
I am hearing from lots of people that I don't need to run tubes event thought they are a tube type tire. How many guys here don't run tubes?
Don't run tubes, I'm at roughly 400 and it seems like these tires will last for 100 or more. I have driven them to and from the track probably 6 or 8 times which is 40 miles round trip, made 20 or more passes and it looks as if they are nearly brand new.
As far as the tube question goes however before mounting them I would suggest getting some straight Dawn dish detergent and heavily coating the insides COMPLETELY and EVENLY then letting them dry in the sun then repeat this step two or three times. I was having leak downs pretty regular on one tire. I then wound up having to screw my tires to the rim so I figured now they are really going to leak right? Well after doing this procedure along with screwing my tires they stay up better than before and are doing great at the track. To some this seems crazy but I got this idea from a 20 year racer and It Works!
