Ag tires & Rims on a 982

Mountain Heritage · #1 08-16-2010, 09:12 PM

So I am kicking around the idea of buying a set of rims to mount a set of ags on for plowing this fall. What is the minimum and maximum size I should be putting on a 982? I can't assume that I can get the exact same size ag tire as turf tire that is currently on it can I? See other people posting ads on things like Craiglist for sets of tires that come off newer Cubs - where the hole spacing on some of the larger "Super" tractors & "Cylclops" the same as the 982 or is ever series have a different hole spacing for the rims? Are ag tires measured the same as turf tires - meaning do you have to take into account the lug being taller and rubbing on the fenders??

This is a new area to me - I hate tires, never could get the sizes down pat in my pea brain. I usually take the tire to the tires shop and say give me the same as this worn out POS!

You need 26-12-12s, which is the same as what's already on there. You also need the super rims. I think the cyclops supers have the same rims as the 982.

GREAT! Thanks Matt, remind me I have to go look in the "special" isle of Craiglist! Cause I am sure there is just LOADS of guys selling this stuff! CRAP! Well, I figured I would be looking for some hen's teeth again soon.

Do I dare ask what those rims would cost new from Cub? Or would I be crazy to even think of buying them new anywhere other than a tire dealer if they had the correct offset as the ones I have?

Just wondering how hard it would be to make your own set of rims from a set of rims from a regular cub. I think the width is the same, the offset is what's different. How hard would it be to cut the center out and re-weld it to the inside to match the 982 rims? Has anyone ever done this? Maybe I'm crazy but I thought about trying it.

I am pretty sure the super wheels are wider. EXTREME is making new super wheels. they have them on there site. They will even put a custom backspacing on them if you want.

I would like to try it too, but my biggest worries are welding the center in straight so the wheel tracks true and weld porosity. It'd really suck if the wheel didn't hold air after going through all of that. I've also heard you can take a 6-12 rim and graft a 7" rim from an 8.50" tire on it to get the right rim, as the 6-12 rim apparently has the right offset on the inside, but needs more rim added to the outside. I would like to try this, but I fear it'd be a nightmare getting everything straight, and I imagine a tube would be necessary.

Wheel is available from CC, 734-3017 and about $100 each.

edit:

jbollis-

They are 8.5" wide with a different offset.

The hardest part would be getting a true cut when you separated the rim you could either use 4 rims to make the 2 you need OR have a sheetmetal shop roll you a couple hoops the width you would need to widen your rims I could widen rims and change to any backspacing someone wanted but I doubt that they would want to pay the cost, I'm thinking in the range of 100$ per rim plus shipping.Id have to check what the cost to have them split in a lathe would be !
Matt I don't doubt for a second that you could build a set of widened wheels !

I was thinking of putting a bare wheel on a tractor and locking the brake on the opposite wheel so only the bare wheel turns, and then marking the rotating wheel with a Sharpie, and then holding a hacksaw to the line as it spins. That's probably going to be pretty close to true. I haven't measured a 6-12 and a 7" rim yet, but I think there's enough there to make one 8.5" rim out of both of them. I happen to have a pair of each of those laying around...

I have had a hand in building some widened wheels. To do a real nice job, you really need a dual chuck lathe. That way you can chuck the wheel in both heads,split it,put spacer ring in, then put it rite back together. nothing moves. It is also nice to be able to weld the wheel while it is on the lathe.

Can use the same dual chuck setup for changing the backspacing. Still might have to adjust the run out alittle, but it would be real close.

if you had access to plasma cutter you could do the same thing as with the hacksaw. You would just want to make a rest/guide for the plasma head, then just rotate the wheel. Make the guide so it bolts on the tractors frame and you could repeat exact results.
