Whats your opinion on the best size rim for mx. Place i will be racing is dirt/mulch. I know that 9x9 has the most options tire choice wise. Also if someone could give me some help on wheel offset for mx that would be nice too.

Thanks

as far as rim size...i have always been told that an 8x8 in the rear provides more sidewall for your tire, which will result in less fatigue on the rider. 8x8 wheels are usually the standard for mx tires anyway... and obviously, a 10x5 in the front. when asking about offset, you need to give a little more info about your quad...are your a arms extended? if they are extended say 2 inches, than running a +3+2 offset in the front wheels may make you TOO wide to race in sanctioned events. If your a arms are extended, or you plan to extend them...you need to buy front wheels that have a +4+1 offset, which should put your front width right at 50" wide... for the rear, if you go with a 8x8 wheel like mentioned above, your offset should be +3+5. i just purchased a set of hipers with the offsets i mentioned above and my maxxis mx tires will be in today...once i get them mounted, i will post some pics so you can decide what you think...

18 x 8 rear tire 3/ 5 offset 20 6 10 front with 4/1 offset. you will pop 18x 9 inch tires off the rim all of the time and it works your suspension alot harder. as for tires if you are running a loamy track mxr6 is th way to go. If you are riding hard pack itp quad cross is hard to beat. Last but not least if you have the cash go for hiper wheels, they are extremely durable and they are the last wheel you will have to buy.

i plan on having itp beadlocks and mxr6 but does an mxr6 come in 18 x 8 and even with beadlocks i shouldnt go wider then the rim with the width of the tire.

Thanks

im pretty sure mxr6 are not available for a 8 inch wheel...i just put on my 18x10x8 maxxis mx's the other day and rode the dog crap outta them....they hook good when i need them to, but slide when i want....the best tire ive ever used....mxr6's are good tires but very very soft...just watch where you ride with them... but as thunder71173 said... try to stay away from the nine inch wheels. and yes the hipers are the only way to go...i have the hiper cf1's and they are simply amazing...ive never seen an alum. wheel that didnt bend...sooner or later, its bound to happen...go with the hipers!
