How wide of a rim on the F1?
 

I have been looking at the Torg Thrust wheels and want to go wide as possible with the rears. I's like to get 16" or 17" by 10". Does anyone have a wheel and tire this wide with stock fenders and no tubbing?

I think this will look very cool. Any feed back would be great!

Merry Christmas!

I`d check with your supplier and leave it up to them to look after it if there are problems after you get it mounted.

I think that is going to be the best way to go. I was hoping to buy rims online. It seems the prices are better there. I'll just shop around. Thanks for the reply.

You can still check with your local supplier, he may have a decent price.
At least you`ll pick up some ideas and cut down on some of the guess work.

John, I am at the same point. My measurement allowing for 3/4 to 1 " clearance to the bedside and the inner lip of the fender indicates that a 265 tire is a reasonable limit on tire width in my 49 F-1. I plan on an 8 inch rim with a 4 inch backspace. I believe that will center the tire pretty well in the fender well. I am running a 72 9 inch F100 rear with a stock bedside and fender in my 49. I think that you need to decide first on maximum tire size (width) that you can run and then buy the correct rim width and offset to properly center the tire in the wheelwell. IMHO a 10 inch wide rim is too wide for a 265 tire.

Thank you for the advice! Sounds like the 265 is going to be it, but I'll check it out too. I want to go to a 16" rim vs a 15" Now that you have the width, what about the height for yours. I think the real big wheels 18-20s look a little out of place on most trucks, but sometimes look cool.

John, I just ordered my wheels. All 15 inch gennie from Wheel Vintique (carried by Summit Racing). I am running 15 x 7 with 3.75 backspace on the front (planning 15-70-235 tires) and 15 x 8 with 3.75 backspace on the rear (planning on 15-70-265 tires). My front end is XJ Jag and the rear is 72 F100 9 inch.

Sounds awesome! Those are going to look great. Please post some pics. There are a lot more tire choices for the 15s. I am looking forward to getting my wheels and tires too. One rear leaks and the just blew out while driving and it's totaled. So, now's the time. I just wish my pocket book would follow as closley to the expenses. Thank you for your help!

I just went to find tires-15 inch 70 series. I like Michelins so I checked out Tire Rack. That led to a call to Michelin-very helpful customer service. Based on my discussion with Michelin, I think going to the 16 inch or 17 inch rim is a better idea. In the larger sizes suitable for our trucks, the availability is better on the 16 and 17 inch tires these days. It looks like they are starting to phase out the 15 inch tires (less selection). A little late for me since my wheels are enroute. I did think about going with the new 16 inch gennie wheels from Vintique wheels but they are about $50 more per wheel. Probably should have done it.

Could this mean that there is a conastoga wagon in my future? I guess that I am just showing my age!

I was afraid this day might come. :(

That Vintage place has some awesome looking wheels. I will have to do some more research now! It seems there are a lot of choices on the 16 and 17, 70 series tires. It gets limited in the 60 series based on my very limited research. I'm sure most sizes will be around by someone. They'll just cost more!

Enjoy it while it lasts, soon you`ll be a senior user, then later on an elder user and finally a senile user like me..... :-X21

Park the truck on a level surface and take the wheels off. Support the vehicle on jack stands with the rear axle at ride height. Using a plumb bob, drop a line from the inner wheel wells' nearest point of interference. Be aware of things such as emergency brake cables, shock mounts, springs, suspension components, etc. Do the same thing at the outer wheel well, making marks on the floor to represent these two points. Measure in 3/4" to 1" inch from those marks, and make two new marks. These marks will represent your maximum tire sidewall width. Measure the distance between them and mark the centerline. Drop another line from the brake drum or rotor and again make a mark to represent this point. The distance between that mark and the centerline mark is the backspacing required to center the wheel in the wheel well.You can do the same procedure for the front wheels, but be aware of where the tires are when the wheels are turned.

This is excellant info. This should be able to help a multitude of people wondering how to measure their back space and how much room there is for tire selection.
