ANOTHER tire question.

notjustair · Nov 7, 2016

Sorry, I'm not done mulling my tire choices yet and you guys always know this stuff.

The 35 Chevy could have come with 6.00-20, 6.50-20, and 7.00-20 as options. It has the old split widow makers which a guy in town always does on my other trucks. My question is - there's a 7.50-20 Samson pretty cheap. Will 7.50's fit on there? It's just half an inch. That shouldn't cause an issue with the duals I would think.

I'm sure my 38 GMC is supposed to have 700x20 but I had 750x20 so I put them on no problem. I can't put my hands on the owners manual right now to check original size. Here is a link of 35 chevy specs for you if you don't have one.

What is your rim width? Most tire manufacturers and many dealers list a range of recommended rim widths for each tire.

I repaired some tires on an old 1963 Chevy 1-ton with the old split rims. We took the tires out to the farmer threw them off the back of the service truck, put the tires on the back of the truck then evening came and we had to bring his truck back to the shop. Half way back to the shop I heard an explosion like a cannon going off. Well the rear left inside rim blew apart while driving down the highway. It cut the brake line so I had no brakes what so ever since it was a single circuit brake system. The inside half of the rim wrapped itself around the frame rail. If this happened to the outside dual hard telling where that half of the rim would have ended up. I would never work on an early split rim again and we didn't repair them at the shop any more either just the split ring type rims would we repair. I would take yours and switch them over to tubeless tires with new or used drop center rims. Those rims -widow makers- are nothing to brag about, it's like playing Russian Roulette. Tires aired up over 1-yes one psi are bombs that people don't realize.

I would recommend getting the old tires off the wheels first, take a good look at the wheels.

If any doubt about the condition, rust, miss matched lock rings, bent, replace them!

Find replacement wheels first, then match the tires to the wheels. You can buy just about any size tire, wheels are going to be take what you can find.

If the rim came apart its because it wasn't mounted right in the first place.

I would guess that with the 7:00 loaded down the 2 tires rubbed together when loaded down. But looked OK when truck was empty. I know that was the way with our 1950 International with 6:50x16 tires. I know the 6:00x20 was a popular size tire as was the 7:50x20, don't think I ever saw a 6:50x20 or a 7:00x20 so I would guess it came with the 6:00x20 new and that small an engine did not have the power to turn the bigger sizes if fully loaded. You are looking at about 4" bigger diameter with the 7:50 over the 6:00 and that would realy change the speed, If never loading I would guess you could get by but have to recaliberate your speedometor. I myself would go for the 6:00x20 size that I would think was standard with the 6:50 & 7:00 being optional. I would not go over a 6:50x20. Even if the bigger would fit I don't think they would look right.

I've got widow makers on two other trucks that get used daily - one to haul grain. I just had new tires put on that truck a year ago and have no problems with them. They do just fine if done right. New rims aren't an option for the 35. I'm lucky because I have six good rims. Some guys have to look for years to find a used widow maker for a 35.

I agree. When I was a kid a small dump truck came into my dads service station. The driver went around checking the air in his new tires. Just as he got up and took one step away, the rear ring blew off! A 1/2 second sooner, he would have been dead!

Come to find out, the truck had 2 different brands of wheels, the tire shop had miss matched the lock rings.

Go to a scrap yard and get a good set of rims. And, they may have some with good tires already on them.....

Here's a picture. If you look at it enlarged you can see plenty of room between the 7.50x20 duals.
