Model T Ford Forum: Forum 2017: Oversize and true 30 x 3 1/2 tires

Which tires now available are true 30 x 3 1/2 and not oversize. I am putting tires on a 16 runabout and the oversize tires just don't let it k right. I have demountable clincher rims and was hoping to put true size tires on front and the oversize on the back. The only true 30 x 3 1/2 I am aware of are the non skid and they are said to wear poorly

I don't think that true 30 inch 30 x 3.5 tires are available. I believe they are all oversize.

I've posted this in the past, but worth showing again.

My dad ran these wheels and tires on his 1917 touring before he restored the original 30 x 3 and 30 x 3.5 non-demountable wheels.

From left to right:

- 1930s or earlier Wards Riverside "blem" or "second" - slight defect in the bead so the Wards Riverside name was ground off - oversize

- 1950 Wards Riverside -oversize - purchased new by my father

- 1920s Trailblazer Cord - true 30 inch

- 1920s/1930s Goodyear - true 30 inch

The Firestone Non Skid tires are the only brand that are close to nominal size. Like you said they wear out rapidly.

The Universal catalog shows a Universal brand 30x3-1/2 ribbed tire with a diameter of 30.25 inches. That's 1/4" oversize - barely noticeable, I should think.

Interesting thought; if you put standard size 30x3-1/2 on the front and oversized on the rear, it would look a lot like having 30x3 on the front and 30x3.5 on the rear. Next question: is it easier to steer with the standard size tires?

I find the biggest problem I have with the oversize tires, disregarding the appearance, is the clearance between the edge of the rear fender and the tire. It is quite close on the 14 Touring, which as far as we can tell, is an original body and original fenders.

Thanks, guys. Looks like with the Universals there is one alternative.
