what size tires do you recommend 1f with 3 speed

[cjgoode]

Posted here since I want to stay old school. My 62 has a 71 1f engine, I assume it has a 71 3 speed tranny also. Looks like original axles. What size tire do you recommend. I would prefer not to switch gear ratio due to the cost and work. Very little off roading no rock climbing, and FL is pretty flat. But still want to be able to go up mountain roads if needed if I take it up north.

So what is the largest tire I can put on and still drive it. I hope to do 33 10.50 on stock rims, but want to get an idea if it will handle that. My jeep has 35's and all stock tranny and axles and it dirves good, but I probably would not be able to go in 5th gear anymore. 30 years ago I knew a guy that put 40's on his toyota. He did not do the gears and almost always had to use the transfer case in low in order to drive anywhere, so do not want that.

So at what size will the ratio start making it difficult to drive and need a different gear ratio.

7,50 x 16

33x10.50's will be fine

 

[My wife said no FJ!]

As far as I know early 40's had 7.00 x 15

Rims are 7 x 15 so looking for tires, but on that point a little education please. The current tires on there have tubes. Do the new ones need tubes also or not. Is needing a tube part of the wheel or just the tire.

they had tubes & new ones need tubes also.

most 4x4 around the globe came with 7,50 x 16
Landcruiser/ Landrover/ Merceds G and the engineers knew why
only the US had 15 rims

if you buy new "vintage tires" * ( same size as your old) you have to buy new tubes too
rim + tube + tire = three different parts

if you buy new tubeless tires no tubes are necessary

* these sizes need tubes

The only Land Cruiser wheels I have that require tubs are my 16" split rims. Non of my other wheels do. That's 16" FJ25, 15" FJ40/45, 15" chrome FJ62 and 16" 100 series.

I also don't think the stock 15" wheels were 7" wide.

33X10.50 would probably fit on the stock wheels but unless you plan on doing alot of off roading I think 31X10.50 would be a better choice. The larger the hill the more your going to notice the taller tires. Even more with a three speed with the wider split between gears.

Fwiw,I ran 36 swampers on an fj45 1f 3sp springover with stock gears for 2 years and my only complaint was the mountain grades.I would not hesitate to run 33's if the motor runs strong.I think a 1f in good tune has plenty of torque to pull 33's...

Keep in mind the bigger the tire the harder is is to stop. If you go to big plan on upgrading the brakes to match.

 

[JohnnyC]

a bigger question is do you want an oem look bias ? or more modern radial type ?

man even though i want to keep my rig stock, i love the look of the 16 inch wheels with some skinny bias tires

To answer your question directly:

Your 15" rim does not require a tube. As John said, the 16" split rim requires a tube.

Tire size does not dictate whether a tube is required or not. Tire design and rim design does. There are tubeless and tube type tires. In the US you can pretty safely assume that it's a tubeless tire unless it is labeled and marketed as a tube type tire. You can run tubes in tubeless tires if you choose.

So, in short you can run a tubeless tire on your rims.

The 700-15 is almost 30" tall, see the "army tire" thread.

There are threads in the 40 section on 33x9.5 tires, check those out.

a)Tire size does not dictate whether a tube is required or not.
b)Tire design and rim design does.
c)There are tubeless and tube type tires.
d)You can run tubes in tubeless tires if you choose.

a) correct
b) correct
c) correct
d) correct... that`s what I do in my 7,50 x 16 radial tires

would chose radial tires, there is a big difference in drive and brake ability.
Radial tires are much safer !!!
would run modern shocks too for example Bilstein.
Drive & brake ability = more safe

I changed too Bilstein (FJ45), color of them terrible yellow
but I painted them black before I mounted them
