so should I try going back to 10 psi and ride it that way until the new tires are broke in? also would there be any way that I could get the 10" wide itp ss112 rear wheels that would match the front ones that I have to fit on the rear by changing out the rear hubs that wouldn't make the rear of the quad more than 47" wide?
Go back to running 10psi
Running these on the front is not recommended, this is only done for 4wd quads.It messes with the steering and you may not have any grip at all in some situations.Been there , tried that , learnt my lesson.
Looked on the ITP website and could not find the 10x10 ss112 rim. I did find a 10x8,4/110,3:5 offset . This will put about 50"+ wide on the rear.
Basically the trx420 hubs are about the same width as the the stock 700xx hubs. The stock 11" rim is a 5:2 offset so a 3:5 will put you at +6" on the rear.
Running a 8" wide tyre on the rear aint too bad, you'll have awesome grip but I would stay outta 5th on the fire roads. It kinda fishtails alot and I mean alot. IMO.
