OK, I'm still new, so be gentle.

I have a 97 TRW400FW that I just got back from the shop..., and she runs GREAT! Not bad for $500!

Now she needs new tires and a few other things, but I'll try to focus on tires. She runs 24x8-11's in the front and 24x10-11's in the rear, stock sizes from what I can determine. What is the largest tire/wheel set I can put on this bike without installing a lift? And should I even consider doing this in the first place?

This is not a trick question, I know there will be performance trade-offs, but what are they, and are they worth it?

No sand, mostly woods, trails and a few stream crossings. Where I mostly ride is an area called Black Bayou, and called that for a reason. When its wet it sometimes gets underwater in some areas. I'd like to go with some 25x8-12's on the front and 25x10-12's on the back, and I found a good deal on a set, but again..., you should always check with the professionals first. :)

what kind of riding do you do ?..you do trails ?..alot of rough stuff like water..mud...swamps ?..or mainly just trails ?..alot depends on your riding style...if your going to be going through some pretty nasty stuff....you will need to go to a larger tire..with big lugs on them < this is how far your tread sticks up >..just make sure the last number on the new tires you get..match your rim size..or you will need to buy new bigger rims..with the same bolt pattern to fit your bike..is your bike 4x4 ?..if so..you will need to keep the front tire size smaller than the back..this is because the way the front transfer differental is..as far as you getting larger tires..that will require you to do a lift..some people like doing this..just so the big tires clear the fenders....and alittle clearance on water..mud..so forth...the only draw back is..it is really rough on the u-joints in your front drive axles if you have a 4x4 ? . the u-joint in your rear swing arm < there is a u-joint right after where the drive shaft comes out of the engine that goes back to final rear differental >...last but not least...too large of a tire will put alot of strain on your ring gear..pinion gear..and carrier bearings from what i've seen and worked on to replace..but..thats up to you.

The riding gets as rough as you want it to in East Texas. Bottom swamps or beat down trails, take your pick. I'm too old and fat to end up walking back to camp, so I keep the riding style to a low roar.:icon_ lala:

The area is predominately timber company land, lots of logs and limbs, and I don't really want to get too far from stock. Just trying to push that envelope without putting a hole in it or tearing up my machine.

You have a 400 Foreman, right? If so, yes, you can run the 25x8-12's on the front and 25x10-12's on the back. You'll just have to buy a set of 12 inch rims. In my opinion, the 400 Foreman needs a little bigger tire as they are already geared pretty low. Also, they sit low to the ground and could use more ground clearance. If you don't go any taller than 25, you shouldn't need a lift.

Shadetree, he will need to stay with the same height tire all the way round, because the 400 Foreman don't have a transfer case.

I found a set of pull-off's that were from a Foreman for $200..., with less than 10 hours on the tires, but I'm not sure of the year/bolt-pattern. The front set did not look agressive enough, sort of knobby, no real tread pattern, which makes me think thay came off a 2x4. :rating05:

I just need to know the limits to which I can tweek without causing more trouble, if you know what I mean. :icon_cussing:

Sounds like the 25-12's would fit/work nicely if the bolt pattern were correct..., but Im still not liking the front's tire tread.


I like the ones in the attached photo..., and they are 4/110's, and $195 for all four! :yeahbaby01:

If they came off of a Foreman, the bolt pattern will be the same for your Foreman. They're all the same. All Foremans are 4X4. If they came off of a 2 wheel drive ATV of some kind, the front and back rims will be a different size diameter. That being said, I like to run the same kind/brand in the front and back on a 4X4.

I picked up the 25-8-12's for the front and 25x10-12's for the rear. Four brand new tires on black wheels, with the center caps, for $200.

Sitting flat, stop-to-stop revealed no streering rubs. Now if she does the same under load on the trail it will be a good day.

Now I need to work on brakes. She has very little in the back, and none up front, which makes putting the wood to her a little scary.

What is the protocol here? Should I begin a new discussion thread on brakes?

Yeah, it would probably be better to start a new thread about brakes. That way anyone searching brake problems will be able to find the information easier.
