Can I use IZSU Rodeo 7-8 inch rims with what tire?

[Screamersusa]

Greets all.
My poor 85 GMC Jimmy with the Desert storm Veteran Humvee engine has been sitting because I cant afford 1400.00 for new tires AND I dont feel safe driving it.
Its got 33x12.5x15 on it now and I just cant get comfy with it on the road. People bast around here like their all in nascar and I cant be drifting all over the road. It's not raised. The eagle rims have been on it since the 80's
I have a set of Rodeo rims that appear to fit... will they take the weight for road use and what size tire should I use for everyday street driving? Or since I don't have a grand to spend (more like 2500) on new proper rims and tires, do I have to give up and sell it? Living almost hand to mouth so no luxury suggestions please. It is sup post to be our "escape from florida by force" vehicle and I really should be driving it.

In my area the proper set of 4 steel gmc rims is 1200 by itself, tires are 1500. The junkyards are picked clean by armies (literally ) of both mexican and hatians who send the parts out of the country. All the 80's blazers, gmcs, and broncos are coming back on the street pieced together (By American drivers) so parts are unavailable. Van and truck parts are scarce in the junkyards as they pick large numbers of the same type part on a daily basis. In some cases they are pulling small parts that make the bigger part useless to someone like me, then sending a team to pull the bigger parts later.
Seems like there's a theme around here in FLA with Americans digging these out of their backyards and putting them back on the road rust, patches and all. Older pickups and beat up wranglers too. Havent seen any VW Things as yet.

Thanks for any realistic suggestions.

The Rodeo wheels would probably have a weight rating around what the stockers on a K5 would have. Really the difference in weight between the two trucks probably isn't as great as one might expect.

My concern would be the wheel hub opening size and the backspacing. Hub opening is probably good...but the Rodeo being IFS I'd expect it to have some deep backspacing. You want 3.5-4" backspacing on these.

So what's wrong with the 33's? Old? I'm trying to discern that from your post above.
Why is it all over the road? Steering loose?

Thanks for an answer.
I just found the missing wheel lock key the prev owner said he didn't have, mixed in with injector parts.
It floats like a boat. It's hard to tell if the steering is loose or not because I can push it from side to side standing still. The tires are like balloons. Normally on a regular veh I can tell the steering needs work. There is also a klunk when making a sharp low speed turn but I can't tell where its coming from.
Obviously if it needs major front end work, Ill have to give it up.
It pulls a trailer well though, and runs a little straighter, strong beast.

I have not checked the hub size on the front yet as I didn't have the key. The back seems to clear ok. It looks like the hub will clear, I'm concerned about clearing the steering knuckle. With 2 jobs I won't be able to check it till saturday.

It does have the Iron (or steel) military engine... not the original aluminum one. And its a 4x4 with internal fwd shifter, not external hub locks.

The 6.2L engines were always iron blocks, C code or J code. Civilian or military.

Sounds like yours has automatic hubs instead of manual locking hubs. Auto hubs are known to suck.

Sounds to me like you have more than just tires going on there. Loose steering, old suspension bushings, lord knows what else. That truck is 25 or so years old with I bet over 100,000 miles on it. Some of that stuff is BOUND to need replacement.

I was afraid of that.

I guess I'll admit defeat. It will be sold. I can't afford that kind of work.
Given the current global climate and recent "Living" virus attacks I guess we'll be on foot if all hell breaks loose. Any time of non-computer fairly bulletproof normally aspirated running vehicle is expensive as heck right now. A rusty 4 cyl wrangler is over 3 grand....not even running! Running, 5k to 10k.
Motorcycles 3k-20k running or not.
The Gmc was bought to save us.... instead it will sink us.

These trucks aren't cheap to own. Parts are cheap but due to their age they invariably need maintenance, often extensive.

No offense but it sounds like you're in over your head. Probably for the best. Good luck.
