so i put some itp mud light tires on the back of my 700xx to match the ones that I moved to the front the front ones are 22x8-10 and the new one's that I put on the back are 23x8-10 so anyway after putting the the new ones on the back the suspension feels really soft. so if i tighten up the preload will it make this problem feel better or worse. i guess I want to know what to do to make the suspension fell like the stock ride again with the 23x8-10 tires on the rear? thanks for the help guys.

Putting tires on shouldn't soften suspension. Check air pressure, probably feeling the flex of the sidewall, not suspension.

I'd say it has to feel funny cause your runing fronts on the rear. IDK how you got away with this before?

well i'm running 6 pounds of air in them now before i was running 10 pounds of air in them and they felt fine the only difference now is that I have my 22x8-10 on the front and the new 23x8-10 on the rear. maybe it's because the tires haven't been run very much and the rubber is still kind of stiff. I don't know. do you think I should put more air in the rear tires?

yea why are you running front tires in the rear that could be a lot of your problem the skinny tire could be causing the rear suspension to flex different

I'll agree with the others... WHY?

I see 2 problems...
1. 23" tires on a 10" rim, you have more sidewall to flex.
2. 6 pounds of pressure will make them sidewalls flex even more.

Off the top of my head I don't know if your tires are 4 or 6 ply... A 4 ply tire will have more flex in it's sidewall compared to a 6 ply.

You also didn't tell us what end felt soft... front or back. I'm guessing the back.... reason... the above plus the back needs a wider tire.

you have to have a wide back tire thats going to plant its self down and get traction plus creat stability wither mud sand or dirt its still the same

the quad felt fine when I had the 22x8-10 on the back and the 21x7-10 on the front. so why would moving the 22x8-10 up front and then putting on the new 23x8-10 on the back make it feel like that? if it felt fine before.

You also said you went from 10psi to 6psi... those 4 pounds of air pressure can make a world of difference in sidewall flex.

so should I try going back to 10 psi and ride it that way until the new tires are broke in? also would there be any way that I could get the 10" wide itp ss112 rear wheels that would match the front ones that I have to fit on the rear by changing out the rear hubs that wouldn't make the rear of the quad more than 47" wide?

Go back to running 10psi
Running these on the front is not recommended, this is only done for 4wd quads.It messes with the steering and you may not have any grip at all in some situations.Been there , tried that , learnt my lesson.
Looked on the ITP website and could not find the 10x10 ss112 rim. I did find a 10x8,4/110,3:5 offset . This will put about 50"+ wide on the rear.
Basically the trx420 hubs are about the same width as the the stock 700xx hubs. The stock 11" rim is a 5:2 offset so a 3:5 will put you at +6" on the rear.
Running a 8" wide tyre on the rear aint too bad, you'll have awesome grip but I would stay outta 5th on the fire roads. It kinda fishtails alot and I mean alot. IMO.

So what air pressure would be good to run in them? I love my 700xx but i wish it wasn't so damn hard to find fancy wheels for it.

i tried itp mud lites on my 400 ex that was the worst tire mistake ive ever made they are designed for utility quads, it handled like shit the ride was rough, i put them on itp ss112 8 or 9 inch rims cant remember but it robbed a lot of horsepower too because the rims and tires weighed twice as much as the stock set up, but they would pull through mud awesome because that what they were designed for,after i put that set up on my 400ex my neighbors rancher could keep up with my 400 and before i could smoke him in a drag race that set up has a lot more unsprung weight and rotating mass which robs hp.:atv:

no it's not really deja vu. it's a different problem now. now it feels like the suspension has went mushy in the turns after i put on the 23x8-10" tires.

1lb can make a huge difference. run those mud lights up to like 15-20lbs thats what i run mine at on the 4x4s

Ok guys i will try running them at a higher psi. I think that I might start looking into running 12"wheels on my xx. For more tire chocies.

Idk wheres your oem rear tires & wheels? I'd try those I bet it fixes both problems. And if you dont like the oem 11" rear rim, I'd go down to a 10" not up to a 12", but these are just my thoughts.

RemingtonSteel: 15-20 psi Wow thats 3x the recomended pressure. Is that just that paticular tire, that needs pumped up like that?

okay so i put the rear tires to 8 or 9 psi and the fronts to like 5 or 5.5 psi and it seems to be better now. I still have the stock wheels and tires but i don't really like the tread patterns on any of the sport atv tires. so that's why I bought the 10" x 5.5" wheels and put them on all four wheels.
