CRC and jaco WGT spec tire
 

Are these the same compund? They are both a lilac compound right

And John's BSR. TM is also a legal WGT compound, performs like the others.

The same "shore" rating of foam anyway and roughly the same compound. It depends on the supplier. I've had great luck with the CRC tires.

what is the spec tire for outdoors/asphalt WGT class? is it the same tire as indoor?

Yes...

Jacos have more flex in the rim giving you a little more grip

.

Thanks for the info, does anyone have a part # for the Jaco spec tires for WGT?

CRC and John's BSR World GT spec tyres are in my experience identical.

The wheel has a bigger diameter and is wider than the Jaco spec. With the additives and carpets we have in the UK, I prefer the CRC build and spec.

Jacos have a smaller wheel, which means more foam left at the same diameter. This may help on tarmac, but I've never managed to get spec tyres to work on UK tarmac tracks.

What we have got to work ok is softer rear foams: greens and aquas. The challenge is to keep additive and grip in the rear tyres. I have some tips if anyone is interested :nod:

There is also QC for WGT spec tires.

It's GQ (hotlapracingusa.com)-they make excellent WGT Spec tires.Jaco was bought out by BSR.

Sure I would love some tips, whats the tip?

Yes, very interested! I have this problem on ashfelt keeping the compound and traction in the rear.

CRC WGT spec tires are made by BSR for CRC. Except for packaging, there is no difference between the two of them.

FYI...BSR recently purchased Jaco outright. But, I do not see anything posted about that event. Will be interesting to see how that develops.
