Inserts or not??
 

I've been running my Trf201 in this seasons Scottish Offroad Championship with yellow mini spikes on the rear and staggered ribs on the front. I've never ran inserts in the staggered ribs but I'm going to try the new cut staggers and want to know if I should run inserts with this tyre? All help greatly appreciated.
Scotty....

Yes, in the cut stagger you need an insert.

We tend to favour a 4wd insert in them, they're rather roomy!
