Default USGT spec tires

so there is a possibility of our club using these for a spec tire in a series next summer. currently its just talk. i have a set but never really got to test them on asphalt much. how do they compare to the HPI vta tires. this is what most of us run in the vta/usgt class that we have. btw we call it scale spec. 21.5 in summer and 25.5 in winter on carpet. need to clarify. we run d compound tires be it either the vta vintage type or the x patterns. both in d compound.

Ill list my questions.

1. Break in time?

2. longevity on asphalt?

3. longevity on carpet?

4. handling with these tires? compared to d compound?

5. Grip compared to d compound?

thanks in advance.

I run them on my USGT car (obviously) and find them to be long wearing/lasting on carpet. It usually only takes me 3-4 sessions to get them broken in (with SXT3.0 tire sauce). I've never run them back to back on the same car with the D-compound HPI tires, so no data to add. The grip level seems to be at least as good, if not a little better than the D-compound HPI.

They do tend to 'balloon' over time, looking a little bit like a motorcycle tire, but this doesn't seem to hurt their speed or handling.

No experience with them on asphalt.

I believe Jacob used them a few times up at Galaxy. He did pretty well with them. I think it would be a better option. I'm getting tired of having to make a tire have good traction when it wasn't designed to have good traction.

At our medium/high grip sugared asphalt track they seem to break in after one run and last several race days. I have never run the HPI tires so I can't compare performance.

The tires jacob had a galaxy were not the usgt spec tire. same compound but different tread pattern. they had more of a block pattern on them. not sure how many times he used them. ill ask him about the performance of them. maybe he will chime in.

I do believe these ere the tires he had. http://www.tqrcracing.com/shop/produ....asp?p_id=7916

hey al. its something being tossed around for the series races for next summer. galaxy isnt on the series so it would not affect them. but the traction is really low at galaxy anyway. not sure if its the prep or the asphalt. but they have low traction IMO. I did get to spray the stuff down one race day and its was alot better. they really dont apply alot of additive to the surface. but if the ride tires do better i would use them there too. but its all up to the race organisers as far as whats legal to use..

Traction is a little better than VTA tires, much lower than slicks-- about 5% slower lap times on our track, which is low-traction, very abrasive asphalt. But the grip levels stay the same all the way though the life of the tire (as opposed to two runs on some slicks we've tried), and this is the most important characteristic for a spec tire in my opinion. They are so consistent, we are considering using them for spec tires for 17.5TC!

On our track they last four+ race days with 17.5TC, five or more days with USGT when the chassis is set up properly and the tires are rotated (once a day).

Charlie Barnes and his CAL RACEWAY in So-Cal has announced he will be using the USGT Spec Tires for his "GT10" class.

The GT10 class is very similar in rules to the USGT (body wise and more) - but is a 17.5 motor class.

This is a fairly good size track, and the speeds of a 17.5 motor are more popular than the slower motor, but we run "Outlaw VTA" with the VTA cars using 21.5's.

I'm glad to see this tire as the SPEC tire, I've heard nothing but good things, and it's got a decent price tag for a complete set of (4).

curious about the pre-mounts from gravityrc - do you use those, or do you glue your own wheels?
how do the premounts perform?
