Does anyone know the track temp. ranges for Take Off RP30GL and RP36GL? I have tried the Take Off web site but it will never load completely.

KT Hobbies has the temp ranges posted. Just surf the tire section and click on the tire you want to look at. Here is RP36.. http://www.kthobbies.com/shop/produc...e8abf491193c01

Also as a general rule for all brands of rubber tires that have numbers in them- the number equals the rated celsius use. Example- RP30 = 30 celsius.

Thanks for the info. Based on my research and testing here is what I have found.
Take CS27 - 46-109* F
Off RP30 - 59-122* F
Rp36 - 68-140* F

Sorex 28R - 68-84* F
32R - 81-96* F
36R - 96-151* F
40R - 120-170* F

Different rubber compounds overlap in temp range. The softer the rubber the faster they overheat. Firmer rubber takes longer to get heat into them. My preference has always been to use the firmer rubber and use tire warmers just before your race. Just my two cents. If anyone has other ideas please post them as this is the best way for all of us to gain track tested info.

One other question? Can you acetone the Take Off CS and RP premount rims to reuse them like you can other rims?

Take Off CS ands RP rims are ABS. Acetone will melt the rims. Trying to boil the rims off will cause the rims to warp.

Re-using rims as a bad idea. They are never straight as a new rim.

AZDemille - Dont forget the RP40's! They work starting at about 120deg and go up to too hot to race!

Could someone please clarify the temperature rating in relation to the way the testing is done.

This has always occured to me as something which more than a few people are concerned with, e.g.

Sorex 36R tyre
According to the Sorex site, this tyre is rated at 35.55 - 66+ celcius (96 - 151F)

My question is - where do you get that reading?

a) track temperature (just aim the temp gun straight at the track)
b) ambient temperature (just sample the temperature in the air)
c) tyre temperature (straight after the race - put the temp gun onto the tyre - to get an operating temperature.

Which one is correct?

And finally, consider the different wear and tear in different classes... Everything else being the same - the modified will run the tyres harder than stock - So you might find that the stock would work better with 32R's and the modified would work better with the 36R's.

Could someone clarify this please...

thanks

The Sorex are rated for track temp.

The only time you'll be able to use a softer tire in stock compared to mod is when the track temp is kinda inbetween say where you'd run a 32 or a 36. For example, if the track is say, 95 deg, then in stock you might be able to get away with running a 32 with no problem but in mod you'll overheat them.

GTIRACER

tire temp ranges are not exact though so some experimentation is needed. For example at So Cal raceway the Sorex 36r is the hot tire and yet the track in never 90d+ and up. Yet those tires always work well there

SCML

So Cal is unique because it has so much grip. You will over heat tires designed for the track temp at So Cal. I've learned that using tires based on track temp works outdoors pretty well, but not so much indoors.

Guys are running the RP36 ands RP40 at SoCal with Paragon Ground Effects traction compond.
