19.5" Truck Rim Specs - Offsets etc.

[sonuvabug]

I've read every thread (I think) regarding going to 19.5" truck rims for our 2001 Ford F-250. I don't want to spend a ton of money for shiny aluminum rims as I would only mount them when carrying our TC as I have two other sets of rims/tires (all season & snow ... both "E" rated).

Although "offsets" were mentioned in passing in some of the threads , I could not find a thread that talked in more detail about the offset specs etc. In other words, if I am going to look for new or used rims, what exactly am I looking for beside a 19.5", eight lug pattern rim? i.e. lug spacing in mm, offset spec, best size to come close to my OEM set-up etc.

Thanks, ~ Bugjr ~

Considering you have an over sized fuel tank and a TC with a large rear overhang, you should definitely get an actual rear axle weight measurement when you are loaded up with water and fuel. I think you will be surprised how much weight you are carrying. You will have a hard time finding any OEM rim rated at or over 3750 lbs and most are between 3000 and 3500 lbs.

Even with just my camper, I can approach 7000 lbs on the rear axle. I can load heavier items to the front help distribute weight, but now I can load items where they are accessible instead of playing load master to keep my weights balanced. I was even able to stay under OEM tire weight ratings while towing but loading was a precise exercise that still brought me very close to the limits.

Can't answer a simple question?

The camper in your sig says 7K isn't enough.

I believe that is per Pair not per rim because you are not going to find a single 19.5 wheel with over 5000 pounds capacity let alone a 16, 17, or 18, and most of them are close to 3400 per rim. My Visions are rated at 4500 per wheel and my per tire is 4805.

My non slide Lance 1055 in the truck bed scales out at 7500 on the rear axle.

If I thought I needed the extra capacity I would just get some newer stock rims, the new Dodges have a load capacity of over 6900 lbs. no need for 19.5 UPS rims and tires

Have you weighed your setup?

I have had a similar weight camper in the bed, and 7K lbs of rear axle capacity isn't going to cut it.

805gregg, you can get super aggressive 19.5s. Take a look at Hankook DH-01s, for instance.

Why would you need 19.5" rims on a 3/4 ton truck? Avoid pizza cutter tires at all cost

The camper in your sig is a great reson to get 19.5's. What do you run for tires? Ever hit the scales?

Looking at your sig, I cannot find a 1071 in the 2003 Lance Brochure, but it does appear in the 2004. It has a dry weight of 3220, meaning it's more than likely 4500lbs once loaded. That seems like a good reason to get 19.5's on a SRW truck, the OEM 17" wheels aren't rated for that and neither are the tires. You can go to 18's but the wheels rarely allow for more than 7200lbs of combined weight, regardless of tires. For the cost it's hard to beat 19.5's when upgrading for a RAW in excess of 7K lbs.

Why avoid pizza cutters? IME they are a much better truck tire than a wide tire.

I had 19.5 wheels and tires on a Class A I owned, I sent a lot of money to get some 16.5 wheels so I could run a decent tire, I hated the 19.5 pizza cutters, felt like ice skates

Thanks all ... very useful input.

We have used Rickson 19.5" wheels and tires for 10 years and 100,000 miles on our SRW truck all over the US, Canada and Alaska. Our rig is very heavy almost 14,000 lbs gross on our Alaska junket. As we often operate on the beach at Assateague Island, Maryland, where only SRW rigs are permitted, we have two sets of wheels and tires.

The 19.5" W/T for long distances and a set of 16" Nitto Dune Grapplers for airing down and operating in very soft sand. The 19.5" W/T are what has permitted us to be able to travel the highways successfully with our heavy SRW rig.

We also have fitted Rancho adjustable shocks. rear wheel air bags, and HD bump stops which have been helpful.

245/70R19.5's (33" tall) are the largest tire size that fit Fords without modifying fender wells or suspension and still be able to use chains on the front or back. If you want a shorter tire, the 225/70R19.5's (32" tall) will also fit your truck.

Cheap wheels and SRW 19.5's don't go well together. IIRC the steel ones are more money than the aluminum ones. It's about 200/ea for Vision Type 81's if you shop around.

A 245/70R19.5 is the most common size as it doesn't have a huge impact on final drive, holds plenty of weight, fits well, and is a common size.

Your 01 Ford uses the 8x170mm bolt pattern.

1600 miles 1n 9 days with my Heavy Lance 1055 running "pizza cutters" over back roads, freeways, washboard, dirt, and I would say they are a way better ride than my old 285/75R16s ever were.
