It measures 28 X 3, so you could use it on a Model N or baby Maxwell in place of 28 X 3 tires. Too small to mount on 30 X 3 or 30 X 3 1/2" rims.

At $447 (USD) each, Think I'll look for regular ol' 30x3 tires. But it would be right for a Brush or a Metz!

David,

The tires Constantine is talking about are 28 X 3.

730 x 130 tires are not the same as 28 x 3 tires.

Per the Coker website, details for the 730 x 130 Excelsior Tire:

SKU: 71212
Tread Width: 3.00
Section Width: 4.70
Overall Diameter: 28.30
Load Index: 76
Speed Rating: M
Max Load Capacity: No
Rim Width: 67mm (which is about 2.64 inches)
Tube Type or Tubeless: Tube Type


They also make a 28 x 3 Excelsior Tire. The details are:

SKU: 79250
Tread Width: 2.30
Section Width: 2.80
Overall Diameter: 27.90
Load Index: 53
Speed Rating: M
Max Load Capacity: No
Rim Width: 1.77
Tube Type or Tubeless: Tube Type

In the for what it's worth department, several individuals who ran Excelsior tires on large and heavier cars (tire sizes 875 x 105 and 895 x 135), suffered repeated failures with Excelsior tires. For larger and heavier cars, the only beaded tires that seemed to hold up were those that were manufactured 20 or more years ago. The design for the "new" tires was changed and they won't hold up to the weight, even with the tire pressure set at 80 psi.

130mm is about 5 1/8". What am I missing? How does Coker come up with 4.70" for their 130mm tire?

I started this post because someone told me that these tyres are 23" rim size; can someone confirm? Royce, how did you come up with 22" rim size?

Constantine,

The OD of the tire is 28 inches. The width of the tire is 3".

The tire section width is 4.7", this is the bulged out section between the tread and the rim.

The rim diameter can be no larger than 22". It may be a tire for a 21" rim, I don't know. But it certainly would not fit a 23" rim.

Royce,
You are so right, I shouldn't try to do math in my head, and definitely not on the weekend!
