depends on your budget....

but, from poor to rich

when the inserts fall out...

once a season

once a month

when lap times fall.....

every run....

me i am right in the middle...

seriously, it does depend on your budget....i can get a month or so out of a set of rp 30, at my track...

There are 2 levels of worn out. The first is a drop in performance and you would check lap times to see that. The second is when the tire has failed as in you can see layers of the tire you shouldn't see (like a webbing on Sorex tires), or when deep grooves or tears are visible on the tire. Sometimes you will get some blistering of the tires but they perform just fine. Some of those might be visible in the handling of your car.

My year old vtec 27r tyres became unpredictable when wrinkles appeared in the tyre. They still work, but only in cooler temperatures.

On our tracks usually you want to look for a groove along the inside edge of the tire.

my practice tyres get replaced when the inserts are showing

race tyres get demoted to practice tyres when the grip drops off or after the race meeting

but i am now using the Sorex32's and the grip lasts right down to the cords and they are grippy on our track

got a set on my spare car that i use for training and they wont wear out !!!!

just stock driving though

If I run the proline blues on the ozite carpet are they about done when you can start seeing a small line or groove on the inside edge of the tire. Side closest to the chassis. I noticed they get a small line around the tire and was wondering if and when that line starts to show has the maximum traction duration been reached . Thanks

i m using sorex tyres for touring. one noticable is tyres thinning. till u see show signs of strings inside. the best is u have many tires to swap around. it help to prolong the playtime & wear.

I'm cheap .... I"m not group A driver..... so, I save money on tires.

I use new fresh tires only for rear. I use older tires at front ( they are rear tires from last race ). I also use 0 camber front and rear.

it depends which car you are playing. How many play 2WD & how many 4WD. the tire wear is indeed different.

The groove is a result of the tyre/insert/belt design - it doesn't mean the tyre is worn out. If you threw out every set of grooved tyres you would be wasting a lot of money.

I agree with what's been said above - tyres are either worn when the laptimes drop, or when you can see the insert! Depends on your budget and level of competitiveness. Crashing once in a 5 minute race will cost you more time than the difference between a set of fresh and part-worn tyres.

I noticed with my Sorex tires when I got my suspension settings right I no longer got the groove on the inside of the tires...I think it was a camber thing on my car anyway. I'll usually see a very very slight drop off in performance once the belt starts showing where it overlaps but not enough to stop running them. I've been running them until the insert shows.

Also rotating your tires will typically extend their usage.
