Those are at least 33s and maybe 36s depending on rim size and 13 inches wide. Quite a tire.

Even though I can't have manual hubs for my situation, I do know some about the topic.

Warn makes a 5 on 4.5 hub conversion kit forJeeps, Ford Rangers and Explorers. It is relatively affordable and reliable.

I think it has more than enough strength for 31s, which is what it was designed for. Plenty adequate strength for 33s.

I think 35s are pushing its limits, but there are many TJ guys at this forum using it with 35" tires for rock crawling.

For a Ford Ranger or Exploder, I think it works with stock wheels.

I don't think it works with stock Jeep 5 on 4.5 wheels, but it might. I'm not sure. It'd be great if it did.

You could get some used Ford Ranger/Exploder wheels and they will fit an XJ, TJ, YJ and so that might also fit the hub kit. So that might be a way to get compatible wheels cheap.

Where this mod gets prohibitively expensive is if you buy new aftermarket wheels. IMO

If I wasn't handicapped, I'd probably want this mod.

The TJ guys are well familiar with this topic. Some YJ and XJ guys too.

To learn more, I suggest Googling "Warn 4.5 hub conversion", or start a thread in TJ section of Jeepforum.

Goodbye gas mileage, acceleration, and braking.

Hello parts breakage.

Hello poverty.

THE Warn does not accept stock Jeep wheels. 31s are ok. There are many reports of 33s being too much. This is one of the weaker kits.

I have no idea what a fat finger conversion is. I do know that a 335 is 100 mm wider than a 235 and 140 mm taller. Nowhere near the same tire.

Has anyone considered heating the fuel, either before the fuel rail or at the injector?

I think "fat finger conversion" means typo (i.e. accidentally hit 3 instead of 2).

Weaker yes, but reputedly plenty strong for 31s, and reputedly easier to install than other kits.

Since 31s are the largest tire I'd ever want in future, this kit would look attractive to me, if I wanted manual hubs.

That said, do you know of other kits as easy and cheap to install that are stronger? If so, please list them. It would becuseful info for the thread.

I think that might be a good idea, if it wouldn't cause vapor lock.

I have heard of hypermilers experimenting with this. If it would help, it'd probably be most helpful in a cold Winter climate. I doubt it'd help in a hot climate.
