i've had mudlites on both quads i've had and they work good, but they aren't the most aggresive. BUT they are CHEAPER that stock tires, and lighter than other mud tires. i didn't even notice any difference in ride with the mudlites on roads or hardpacked trails

 

I just bought a set of 27" vampires and am very pleased with them. They are really good in the mud. not to bad on trails either. the only thing about them is if you ride in the creek you have to be gentle with the throttle or down you go because of the sand. Two weeks ago i tried to croaa a swampy mud hole and didn make it but last weekend i went through the same hole with ease. just my opinion

 

it all depends on whether you want to keep the stock rims or not wanting to add spacers on what width in the front you need to stay with. much wider then stock will need spacers or aftermarket rims. highth wise i wouldnt go more then 27" or you wont be able to turn them as easy in the mud. as it is you will(should be)using low range more. i put my stock 26"pxt's on the 450 and they do better then the 489's for sure. but when they are worn out i'll buy something esle w/ thicker side walls. the mudwisers are about the same in mud as xtr's but their harder compound causing vibration.

 

as far as size goes...like someone else said, more than 1 size wider will rub in front. I made custom tierod end to move them inboard, but spacers work well also. And consider a clutch kit cause even 1 size bigger will take noticeable power to turn. What is tolerable is up to you. If you ride alot of trails , make a "sane ' decision on pattern and size (Executioners are about as harsh on trail as I would go) . My buddies mudlites are 10s in front but are "rears" so the lugs are more open also. from expierience ,with your quads body style 27s will fit without much rubbing , 26s will not hit ,remember , Bigpappa, you have radials so the pricier but EXCELLENT mudlite radials are a nice choice. I know 4 people with these tires they are GOOD in mud and real nice on the trail

 

to me i love my xtr's for the ride and handling. there pretty good in mud as well.

 

i have the mud lite xl on my hawkeye and they did great this past weekend.
i got in some really deep mud and they were turning up new rut and got me thought

just my opinion

 

I have heard that the Mud Bugs and Gators are rough and cause a lot of vibration on hard pack?? I just put 27" mud bugs on my unit and they don't seem very rough at all, even when plowing.

 

i know a guy who had mud bugs on his cat and he said they were great traction but didnt wear very good. my friends piellie mudwisers real vibrate on hard pack at lower speeds.

 

i have a 2002 arctic cat fmf pipe jet kit and ijust got 26in kenda with itp type5 wheel think i will have the power to turn them?

 

Polaris500Sportsman,
any power loss issues going from the stock 26's to the 27's?
