When to retire rubber tires on carpet?
I am new to TC racing and I was wondering how do you know when a tire has lost its edge or is no longer worth running anymore--specifically talking about rubber tire on carpet. This is assuming it still looks "ok". I can't tell if the tire goes away or the car caught a tweak. Is it just something that comes with time and experience or is there something in particular to look for?

Similiar vein to what b20 said, after about a month of running (practice and racing) its time for a new set. Our RD is a heavy TC guy and quotes 30 runs (we are using Sweep 28 QTS). I notice when mine start to develop a ring on the inside edge its time for new ones and that older tires feel "loose" (or flabby maybe?).
Before I make any setup changes I try new tires first as that has usually been the fix it seems. This should hold true if you only race at one location and traction is consistent.
Regardless, do NOT rotate your tires more than once. Tires tend to wear differently depending on the corner and moving them around creates odd handling (different from worn out tires).
PS. One additional item. This is for sedan tires. VTA tires, drive till they pop, then think about replacing them!

When your laptimes drop off. The clock never lies to you. It will tell you when your tires are done.

thanks for responses. It seems to be Sweep QTS 32 at our carpet track. I jist noticed the other day practicing alone ( track was loose) that by the end of the day--even saucing each run with SXT--the last pack the car felt very greasy. This was after 1 race day and a full practice day on the same set. Compared to off road, these TCs are SO sensitive to tweak and setup that I wasn't sure if it was tires or some issue with a tweaked car!

Me and my son been running on the same sweep 32 spec tire we bought and raced at the Cleveland champs this past nov. Thats 23heats , 7 mains, and atleast 30 runs for practice.
I rotated front to rear 1 time . Only setting we have changed is camber as track gets sticker. This past weakend my son told me his car was loose . Come to find out he had both front tires riped open on outside edge. Wished every tire in my box was from that race ....
anyome got any they didnt run or still show seam that say 2013 Cleaveland champsill buy them

Why rotate only once? Why not after every single run. Rotate them in a cross box pattern similar to a car.
LF→LR. LR→RF. RF→RR RR→LF. Every 4 runs the tires will be where they started.
If your track is like mine the FR tire gets alot more wear on it due to the layout. Without rotating it would wear out long before the LF tire and ruining the set.

Tires are cheap, we aren't talking hundreds or thousands like real tires which it makes sense to rotate. Ever notice how 1:1 race cars don't rotate their tires in the pits but go for a fresh set?

Jay: I was obviously at the same race as you. my first TQ run was on 3 week old sweep 32's. The car was ok but felt inconsistent. my last TQ run was over a lap faster on brand new tires. The car felt the same every single lap. I full sauced with SXT all day on all my tires. The first tires I ran had the wear mark on them and i expected them to be slower especially because the sidewalls had become way too soft. I would say if you are killing tires quickly it may be overheating due to setup. Setup is important to onroad when you use a spec tire. I be if you put a sorex28 on your car you would have thought it was the best setup ever. In local offroad you have a choice of 50 tires so setup may have a larger window because you can just pick a softer/stickier tire.

Actually on full scale road racers, the tires are measured and matched back into a set by size. This is called a set of scuffs, depending on wear the tire may not end back up on the corner it came from.
