Porterbuilt Tire/Wheel sizes....20's & 22's

I know the answer is buried in one of these posts, but I can't find it.....

A couple of the Porterbuilt trucks (including the Panel) are setup using a 20" wheel up front with a 255/35-20 tire (approx. 27.03" diameter) and the rears are a 22" wheel.......but I can't find the tire size????

I think I've seen where the rear tire diameter was described as 29" in some discussions....but the closest tire I've found to match that is a 285/35-22 (approx. 29.85" diameter)????


Anyone able to clue me in???


Thanks!

Thanks! That puts it at 29.30"......pretty close to the 29" I thought I'd remembered reading about.

Even better.....accurate info!



Thanks, in case you can't tell I'm still "studying" and trying to understand as much as possible before placing my order.

At this point, I'm basically settled on a C4 Dropmember with the C4 rack & pinion. Will the ART Air-Bar (bolt-on 4-Link) get me all the way down in the rear on a 29" tire?.....or should I chill-out and wait for your rear suspension design to be completed?

I have never considered the C4 as "settling" I will be running the C4 rear, but I am torn between the standard dropmember and the C4 version. Only because I have invested in the front already, so I have some of the parts on hand.

Re: Porterbilt Tire/Wheel sizes....20's & 22's

If you were running a solid rear axle (which I am)....what's your take on a good rear suspension setup??

The Air-Bar looks like a well-engineered design, and simple because I don't have to do much other than just bolt it in. However, I don't know for sure if it's intended to "lay frame" or not.

I know that a certain amount of cutting is going to be necessary out back to get all the way down (driveshaft clearance, frame notching....maybe more) but I'm hoping that by staying with a decent diameter tire, like the 29" variety we've been discussing.....the mods won't become excessive out back.

Re: Porterbilt Tire/Wheel sizes....20's & 22's

I am waiting on Air Ride's new Strong Arm kit for the rear to get here so I can play with it. I have a 62 panel (my new shop truck ) I set on a 66 Sub. frame and it has a Dropmember up front. I will be putting the Air Ride stuff on the rear and will find out what is needed to get it down. I do know there will be "extensive mods" to make it happen... if a big notch is considered to be "extensive". The 63 panel referred to earlier has a c-notched frame and is as low as it can get with such.

You had mentioned towing with your burb... it will be quite a bit of work to lay frame and keep the structural integrity of the chassis in order to safely tow.
