So I am picking some 99' factory aluminum wheels to replace the 98' factory steelies. The 99' came with 12's on the front and rear. My initial thought is to wrap the new alloys with some Tusk Terrabites in 27x9-12 (26.97 Dia., 9.02 Width) for the front and 27x11-12 (26.94 Dia., 10.98 Width) for the rears. Based on the calculations I should have room/clearance, although a bit concerned as I read that the offset may have changed a bit in 99'. Can't find specs on the offsets from 1998 to 1998. If someone can shed light on this I would greatly appreciate it.

Based on the room between the rear tire and rear portion of the foot-well, 28's don't look like an option. Also, anyone have experience with the Tusk Terrabites?

Front:
Now 25x8-12 (24.95 Dia., 7.99 Width) vs.
New 27x9-12 (26.97 Dia., 9.02 Width)

Rear:
Now 25x10-10 (25.00 Dia., 10.00 Width) vs.
New 27x11-12 (26.94 Dia., 10.98 Width)

You can run 27's on the 600 with clearance. I ran 27" tires the whole time I owned my 600.

On factory wheels, you cannot run wide tires on the front. They'll rub the tie rod ends. I ran 27x10-12 tires (10" wide) on the front of mine and had clearance to spare, but I had ITP Delta steel wheels. I believe 9" wide will fit on factory OEM wheels.

There are hundreds of good reviews on those tires so I have no doubt that they are a great tire for the price. Or just a great tire in general. But in going through the reviews all most all of them are from big sxs owners. Since they are 8 ply tires and intended for sxs they are going to feel real STIFF on your 600. Had you considered that already?

Thanks for the reply and pointing out they are 8 ply. To be honest I totally missed that.

My riding buddy has 27" Mudlights on his 600 not sure of the year with no problems. As wheelsquad said might be stiff ride with 8ply's. With that SRA you might want to consider a 6 ply radial tire.

STI Black Diamond XTR are a 6 ply and available in the sizes you want, for only a little more $$ than the Terrabites.
