I would say either of those wheels would work. Using a tape measure I think my +38 offset, with a 10 inch wide tire, will fit. So a +45 or a +50 (which I believe is stock offset) will definitely fit. You could also use 4 stock front wheels with 1.5 inch spacers in the rear and be gtg to but not on beadlocks. I could sell you my MRT setup if you want to try it? They have over 50% tread life on them. Some of the reason I went with a wider tire in the rear, on the MRT, was due to width differences front to rear. But no matter how you slice it the rear hubs are 3.3/3.4 inches narrower than the front, which is the reason for the 1.5 spacers. The spacers are not really needed persay. Some tires and offsets in the rear will rub without a spacer (probably not 30s). Your machine will actually steer better without spacers in the rear but tip over stability is not as good. If you want fast and nibble then a lite 30 is a good choice. I think the MRT, with Kevlar I have, weighed in at like 32lbs. My 32x10x15 Terra Masters weighed 39lbs. My 32x10x15 Rockzillas weighed right at 42lbs. If memory is right, my 30" M1 Evils (which are heavy) weighed more than both of my 32inch setups. I believe my System3 Wheels weighed right at 16lbs. In case you care about lbs....I think I have some Raceline wheels that have an above +40 offset....I'll have to look. The 30" M1 Evils are mounted on those.So if im not mistaken, if i ran System3 SB-4 15x7 4/137 6+1 (+45mm) wheels with MRT 30x9x15 that should be same profile as the stock fronts. Then same wheels/tires rear + 1.5" spacer should give the same out width in the rear as well...if anyone wants to check my math? Im not quite as sold on the rear numbers looking right.
ahh or even better. STI HD9 15x7 4/137 6+1 (50mm) wheels with MRT 30x9x15 and then 1.5" spaces on the rear. that .2 inch difference between the System3 and STI might be kinda helpful i suppose. The with what CID said, can get away with a bit more slop in the tires themselves giving some other options similar in size. id like to stick to the 30" ish though.
And that makes total sense, @CID if the rim is within 65 even if the tire bulges out it will get inline if forced thru.
I believe he's thinking about running spacers on the rear only, to keep the front and rear track width the same with four 6+1 rims so he can carry one spare.If width is critical, why run spacers? Have no experience here, but it seems that this is purely cosmetic and i'm pretty sure i could never see the difference unless things were clean, straight and level
Lil_Steve wasn't running rear spacers and even after he told me, I still couldn't see that the rear was narrower with 4 front rims.
@Lil_Steve do you have a stock front and HD9 front with no tire that you can measure the offset differences? (like cement up to mounting surface)
Thanks for responding @Lil_Steve . I was wondering if I would need spacers when I switch the back rims out to front ones. I really didn't want to have to use them.Yeah, I bought the spacers, tried them and pulled them, never liked the idea of wheel spacers. After trying STI bead locks in different offsets, I went to 4 stock front wheels and have been happy with that set up.
The HD9's are long gone, so I'm unable to compare offset differences between the 2.
Dang, thanks @Hometeam ! Those pics are awesome! the MRT i was looking at are the same you ran in front i think; Race 30x9; id have to find wheels to run them on all 4 and 1.5" spacers i think but the size looks about right to keep them under that 65 width. Good to hear they worked well.
The next thing i need to understand is the rim offsets hah. its a whole new world
I was in the same boat after buying my Talon. So many options and having to worry about being 65" or less. After seeing my son damage 2 stock rims I decided not to use my stock rims. Also wanted to be able to easily throw the stock rims and tires on if I needed warranty work done. In the end I went with GBC Kenati Mongrel 30x10-15 on 5+2 rims with a spare that I rotate in. I'm right at 65" in front, no rear spacers, and have passed through gates. I'm very happy with them after 2000 miles. With probably 50% of those miles on pavement, the tires still look new.Edited to add: 1000x-4 is what im looking at.
Caveat, im still looking to buy but trying to do my research ahead of time on what id buy up front. I have read through the 10 pages of posts here and still have no idea what im talking about.
From what ive read stock wheels/tires are not great. I will be riding in WI and their req is under 65" and apparently some of the trails/bridges force that req on you via gates and obstacles. Id also like to consider all 4 being the same so i can carry a 5th as a spare. Id like to maintain as much geometry as i can.
Id like to make a run all the way up the wild rivers trail and hit some of the offshoots and will be 100+ miles out so a spare seems like a good idea as i will likely be solo most of the trip.
Thanks again!
Nice Thanks! Which rims did you end up with? I have been looking at Mongrels and Terrabites for tires and keep waffling, or MRT Moto Race. I am a bit of a chicken on the beadlock topic and kinda want to stick to non-lockers for what ill mostly be riding, but only because i dont want to babysit leakage. based on what im hearing the +38mm seem to get people pretty much right to 65". I did run into Black Rhino rims which offer a 15x7 in +51mm which adds a bit of width from stock due to the extra .5 inch rims but is kinda looking like it might be a non-beadlock option without jumping all the way out to +38s. Though going +38 adds a TON of options....i really like the look of the method bead grips to maybe walk the line.I was in the same boat after buying my Talon.
