Tire Recall and changing rims and tire size

[Clayboy]

Was just notified BF Goodrich is recalling some of their Commercial T/A tires. These are load range E tires and happen to come in the factory size original to my/your D250 - LT 235/85 R16 120 Q LRE. Three of my tires are affected, check yours and be safe. Learn more about the affected tires at - http://www.bfgoodrichtires.com/voluntarysafetyrecall



Since I have to change my tires, I have been thinking about going with a later model 17 inch factory rim for my D250, but I have some concerns about what if any calibration needs to be done for the speedometer. OEM tire size was 235/85/16, I am sure if I did put 17's on, but went with a smaller aspect ratio (profile size) this would help off-set/eliminate any speed indication variance and/or clearance issues - or am I wrong? Any recommendations are appreciated. Thank you!

The 1st gen D250 axles are too narrow for the newer wheel back space. They set in too far and look goofy, I tried on mine They won't work as a trailer spare either, they hit the springs.

hmm... any experience with a wheel spacer? What about any aftermarket rim? I love the old school look of the originals, but they are way too heavy. On a seperate note, I noticed you have a Pac Brake on your 91. 5, did you happen to install yourself? If so, was it pretty straightforward? I spoke with one of the guys at Pac Brake, I know I would have to change my springs, which I think are included. How do you like the performance? Thank you!

Yes, I did the install on the Pac brake, it is easy. It is the direct turbo mount and comes with a new down pipe. It is also the old style (non PRXB) so it is RPM dependant. I did not change out the valve springs so it is only rated at 140 retarding hp, with 60# springs you can get 190 hp. I don't haul heavy with it any more since the purchase of the '01 so it works fine. If I were to do it over I would use the heavy springs. There is a big difference in performance on the '01 v/s the '91. Best towing mod there is! If you have an auto it will need modified, my rigs are standard.



I am not a fan of wheel spacers. As far as after market, I am sure there are many available, just try and stay with factory back space specs.

I did this with my truck.



The factory 235/85/16 is almost identical to a 265/70/17.

So I got a set of American Eagle Baja wheels that were used (off a gen 3), cleaned them up, and this was the result!

I do not have any width issues, spring rubbing, etc. I dont remember a D axle being different than a W rear axle. As for the front, I cant comment as I have never played with a 2wd tire to spring measurement.



As for spacers, not recommended. Places the load in incorrect areas resulting in incorrect bearing load.

That is because those wheels do not match the factory baqck spacing of 3rd gen wheels. They are probably 4. 5 inches instead of the 6. 25 used on factory 3rd gen wheels.



A set of 4. 5 - 5 inch x 17 inch 3rd gen wheels will work fine with a standard set of tires. Wider tires need less backspacing or they rub.
