Picked up some 450ex hubs (4/110), 2" spacers and new 8x8 rims. Wondering if anyone has tried 8x8 rims on there atc70 and what tires they used? Also if anyone has any pictures? Or should i go with 8x6?

Well, I have tried a lot of tires and wheels and overall I find the 8 x 8 wheel just a little too wide for any tire that fits on an ATC 70, and I have tried it with multiple 18 x 9.5 - 8 sized tires.

The 8 x 8 always stretches the tires out to where your outer rim lip is vulnerable to damage and it makes the ride much worse as the tire sidewall is pulled out so much it can't flex properly absorbing bumps. This is critical on a high powered rigid frame 70 when going over 50 mph like mine do.

I had the exact same 2 ply tires on a set of 8 x 8 and 8 x 7 Douglas Wheels then rode them side by side the same day with a friend switching between my two ATC 70s. Both of us immediately commented on how much more harsh the ride was on the trike with the 8 x 8 wheels when we rode that 70.

I have tons of photos of tire and wheel combinations but in the end I recommend a 4/110, 8 x 7, 3+4 off-set from Spangler's with an 18 " tire for best flotation, grip and ride comfort.

Here are the setups I run today both with Douglas 8 x 7 race cut wheels which is plenty wide for a 70.

Braaaap!

Worst tires and wheels ever! Crappy Holshot tires and cheap ebay 8" Boss wheels. Came on a trike I purchased and sold them after only one test ride. Don't buy either!

Great info! Thank you for the reply and photos. I ordered a set of the Duro tires last night after seeing your thread on 3wheeler.

For now my plan is to keep it 70cc as my boy is turning 4 and anymore power will just get him hurt..sooner.. What size tire are you running on the front and how are you mounting a 4/110 rim on the front?

I have a soft spot for that 350X. My buddy had one in junior high. Neither of us were big enough to start it consistently and I still have a knot on my shin from the kickstarter kicking back. That thing was a wheely beast. We'd carry a rope while riding and I'd pull start it with his ATC90. As unsafe as it was sending little kids out on three wheelers, I believe the 90 was way more dangerous than the 350. The 90 would try to flip you over in every turn. The 350 just required a stab of the throttle and you were power sliding like a pro.

Typically I run a 18 x 7 - 8 Maxxas for the front. The red 70 above with the 350x had a Duro 18 x 7 -7 and a 7" Xowner front wheel. Have run an 18 x 7 -7 Duro Thrasher front tire that rode fantastic as it is a 2 ply radial tire. I have one brand new one if you are interested.

For front hubs I am running the Spangler's billed 4 bolt hubs and aluminum axle spacers to save weight.

Maxxis 18" front and rear tires.... personal favorites

Duro 18" tires on orange trike.

Thank you for all the info! Next question is what is the trick to un mounting and mounting tires?!

Take them to your local atv dealer and let them do their magic with the tire machine ....... seriously.

I have some of the best tire levers that make manual tire installation possible with some soap and water. But it can take 2 people and a few hours to complete. However removing tires and getting the bead to unseat can be extremely to impossible even using special Motion Pro set of bead breaker bars. Much rather watch the shop guy pop everything on and off in 10 mins using their machine and I'm back on my way. Less tire and wheel damage too.

I am thinking about getting one of these from harborfreight for 45$ Got the tires yesterday!

I have one, and would not recommend. You can get by with tire irons, soapy water and a 2"x6" with a Cresent cut out of the end to brake beads. Let me see if I can find the video.

Looks ghetto, but it works on dry rotted 1980's atc tires. I have been lucky enough to have access to commercial tire machines and this works better.

Thanks for the videos! Local tire shop only charges 8$ per wheel, but damn it ads up quick..

SS LS1, have you had any issues with the axles bending running the wider/larger wheels? I want to ride up on two wheels but worried the extra leverage is going to cause issues.

Works great!

Sorry for the late reply..... no I have not had a single problem with bending anything from axles to hubs or wheels hitting bumps or riding on two wheels. I ride the snot out of my 70's from sand paddle shock loads to hard core ditch riding and still not a single problem. Plus I'm a big guy at 6' 4" 250 lbs so no featherweight rider either.

Hello can you tell me what size tires that are the orange atc with the tread in a arrow pattern front and rear. Thanks
