Dayton Wheels

[Speed]

Hi all;

Another newbie question for ya.

I'm wondering what size wheels are available for a 1938-40 EH. It has 10.00-20's on Daytons now,but are all Dayton hubs the same size as far as the wheel size that will fit? Are Daytons available as 22 or 24.5,and could they be used on this old truck?

Thanks for your patience-I'm learnin' as fast as I can...

I asked a similar question a while back and know this much:

20 inch dayton hubs take 20 inch tube type or 22.5 Tubeless wheels

22 inch dayton hubs take 22 inch tube type or 24.5 tubeless wheels

24 inch hubs take 24 tube type only, there isnt a tubeless 24 inch.

The wheel mounting for daytons havent changed for a very long time so new 22.5 rims should fit.

Thanks Thad;

Cool-so theoretically I could upsize to 22.5 inchers,tubeless. Guess next I need to find out what size 22.5 would be substantially taller than the 10.00-20. I'm not very familiar with the OTR truck tire sizes-my trade was car/light truck tires. I'm trying to back-door a little more mph and less rpm,even though I don't know for sure yet that the stock mill will have enough suds to carry it...

I dont know how similar 10.00-20 are to 10.00R20 in terms of diameter but 10.00R20's are around 42 inches in diameter. 11R22.5 are about 42 inches in diameter and 12R22.5's are about 43 inches in diameter.

My B had 10-20's on it, I put 11r22.5 Radials on it getting rid of the split rims.

MadMacks;

Thanks for the info-it looks like about the only advantage to going to 22.5's would be availability of tires and better handling. The current tires are pretty good,so it'll probably be awhile before a change is necessary.

Freightrain;

Thanks for sharing that-it's proof that the wheels will fit.

Did it change your road speed any? Sounds like the two sizes are so close to the same height it probably didn't make a difference there.

22.5 rims do fit in place of 20" tube rims Thad is correct. you can put either 11.00-20 or 12-22.5 tires on it to pick up a couple mph's but they are a heavier duty tire with more plies and the price is also quite a bit more expensive and the selection is a little smaller than the more popular 11-22.5's and 10.00-20's

Thanks for letting me know that. Since my 10.00-20's are still okay,I'll go ahead and hang with them. I guess the next possibility would be re-gearing the rear end.(How far before and after this truck are the punkins interchangeable??) BUT-I'll wait until I can run it out and see what I'm working with before I worry about that. On my cars and pick ups,I've always used taller tires as a way to improve my road speed/rpm situation,but in the big truck world,it appears the options are a lot more limited. There are still options to look into though. For now,I'll concentrate on learning about Mack EH's and pulling a plan and design together to get a good flatbed and boom built for my truck. (THAT oughta keep me busy for a few days!)

Thanks again for your input,guys!
