XRAY - Model racing cars

Just to make sure guys. That I am understanding this right.

Tire inserts.

You run softer inserts on tracks with less grip and harder inserts on Tracks with higher grip.

And if you run soft inserts on a track with lots of grip you will over work the tire. Heating it up to fast and lost of wear ???

And if you run a Hard insert on a low traction track the car will slide, wheel spin


Does any one know what the differences in air gaps between the tire and the insert does ????


Also xray has rims available in soft, medium ,hard. When should u use a Softer rim and when should i use a hard rim ????


Any Help would be great Cheers.

softer insert-more surfuce of tire which is touching the ground or carpet,so its giving more grip,but car is slower just a little bit
harder insert-less surfuce of tire which is touching the ground or carpet,its giving less grip and car is faster

with harder inserts they are wearing faster(but im not sure...)


there is almost no air between inserts and tire:)

insert are making shape of a tire and they are giving "hardness"

Thanks for the reply

i forgot about the wheels-.-
the softest wheels wont break,they CAN just change their form due to some big crash,but they will NOT BREAK
the hardest wheels will break only in BIG crash

i recomend the softest or medium
