33x10.5?

It is kind of funny how 4X4 styles have changed, this used to be the typical 88 tire size:



they almost look silly nowadays...

yorker, do you or anyone have an idea of what a stock wheel & tire was for the series iia swb?

[leafsprung]

Stock 88s had several optional sizes. Most got 6.00x16 some got 7.00x16 Thats until the 15 inch rims came standard

[yorker]

I think some had 6.50 16s too?

I think back then they just put enough tire on the vehicle for the loads they thought it would see- you only saw them stepping up in size to accomidate a higher load range. 6.00 16s and 7.00 16s were common 1/4(to 1/2) ton type vehicle size. 3/4 ton vehicles seemed to get 7.50 16s, and 1 ton to 5/4 tons got 9.00 16s.

When you have those stock sizes on an 88 they almost look silly by today's standards.

Dinky!!

I'm not sure what the stock 15" tire was- I seem to remember h78 -15? I know I have used 7.50-15. ndcc's. http://www.carnut.com/specs/tires.html

I think those are 7.10x15s (pictured). Thats a NADA deluxe hardtop. Ive not seen 6.50s in the manuals, but Id be really surprised if they didnt find their way onto trucks.

You are probably right about the 6.50s, I've seen them on US LRs but they might not have been technically OE fitment.

It is kind of funny to look back through the older stuff on tires- I remember reading some period literature once about military jeeps and they were bragging about how much superior the later 7.00 16s were to the ww2 6.00 16s in terms of flotation.

i was hoping to get a toltal hieght out of you guys so i can compute the stock tire circumfrence and compare it to the circumfrence of my 235/75 16s.

235 is mm equals 9.25" wide and the 75 is 75% of the with equals the hieght of a sidewall which is 6.94 inches times two plus 16" diameter of the rim makes the diameter of a 235/75 16 29.9 inchies times pi 3.14159 means a circumference of 93.85 and comparing this to the circumfrence of a stock will tell me how off my speedometer and odometer are, right?

[leafsprung]

total height varies by manufacturer. between 28-30inches

that's about where mine are. did they install differant speed cable dive gears based on the tire size? or where the speedos always just an approximant reading?

[leafsprung]

different speedos.
