Hi
I want to upgrade my rims for ITP SS212 items. I have the choise between 4+3 or 5+2 offset.

I'm quite satisfied by the actual setup of the machine and don't want to change the width . (+ my trailer and narrows tracks in France )

I don't know what are the stock rims size :crying:
I've made some measurements but can't find something revelant

Can you help me please ?

Merci

5+2 are closest to stock (maybe just slightly wider than stock). 4+3 would stick out 1 inch wider than 5+2 PER WHEEL, so your machine would be overall 2 inches wider.

On every machine I've had aftermarket wheels on, I've had 5+2 and they were all 1" offset from stock which gives you a 2"wider machine. I mistakenly was sold 4+3 offset one time and they look awful. They stuck out so far, the center of the tire's tread was lined up with the outer edge of the fender. They have no place on any machine I own.

Personally I hate the offset of 5+2 but I do like the looks of the wheels. I hate getting mud all flung on me when I'm just on a leisurely trail ride. Offset wheels mean more mud.
Plus.. offset wheels add to your turning radius. The wider the rear of the machine the more the speed difference in the inner and outer tire required for smooth turns. BUT because Atvs have a locked rear axle, the tires scrub off the speed difference. Hence the ripped up ground when turning. If you increase the scrubbing of the tires you reduce the influence the fronts have over the back tires.
Also... ideally the front steering wheels should have their center centered with the line drawn though the upper and lower ball joints. This gives ideal steering with them least effort and handlebar whip when hitting rocks. If you move the rim outward. The tire center no longer pivots on the ball joints but rather scrubs though it's motion. You actually are pushing the tire forward and backward as you turn it, increasing and decreasing your wheelbase. It's only small amounts but it adds up to increased effort and more wear on parts.
