Default air gap & foam insert


Can someone advise what is the significant of Air Gap between foam insert and tyres ?

Noticed that the newer inserts seems getting thinner and thinner.

The air gap is supposed to increase traction, it'll let the tyre "flex" a bit mor when you put down the power.

From how I understand it, more airgap means more flex which means more traction. (think of the "wrinkle wall" tires on a dragster)

If you want to get rid of airgap, either use a bigger insert or wrap tape around the rim until it feels good.

or you could use something like Trinity's Bomb gllue (for tire inserts) to gllue the insert to the wheel as well as the tire carcass if you want. You could also use slightly wider rims or inch ups to decrease the airgap.

Having an airgap in the tires is a drivers preference. i like a little, but if ihave no air gap, the inserts seem to heat faster.

For my sorex 36's, I like to buy 26mm standard rims and HPI 24mm inserts, this gives just a little less air gap then usual.

Glueing the insert to the tire constitutes a capped tire which is illegal for ROAR and IFMAR touring.

I've actually noticed the opposite trend of fatter inserts. I still prefer Yokomo inserts over all the newer, fuller inserts. The baginess makes the car a little more predictable at the expense of slightly irregular tirewear.
