After purchasing this truck my first priority was new tires. Just a city / highway truck, no offroading. What I immediately encountered was similar to my experience with a recently restored '92 Celica Convertible...very limited choice in the original tire size of 225/75/15. Also, the 15" rims on the truck were rather shabby looking, missing two caps. I liked the look of the stock 16" rims and was fortunate to find a set at a local boneyard which I acquired and am in the process of repainting. Got a great deal on some stock size 265/70/16's from Tire Rack. Now I must deal with correcting the speedo...the larger tires as most of you will know throw it off by about 8mph on the plus side.
Yes, I have already researched this, here and elsewhere but many of the references I came across were rather old. So I'm looking for fresh input and first hand experiences...what I hope for is the most practical, most accurate, easiest to install. I have seen and read about the SpeedoHealer and Yellow Box. But if this vehicle had an option of 16" tires wouldn't there be a way to re-gear it? I would really prefer to get this accomplished without yanking the dash / kickpanels apart if possible. Really need to get going on this ASAP due to it being January...I live in Ohio...and the tires on the truck are in no way Winter worthy. Supposed to be 68 degrees tomorrow...but that sure ain't gonna last long. Very much appreciate any and all help and info for this issue...

I would start by getting a GPS reading compared to the speedo and go from there.

On my stock 00 Limited I replaced the stock 265/70/16s with 265/75/16s assuming my speedo was going to be off but not knowing by how much I just checked and my speedo was basically right on the money at 60-65 so evidently my stock speedo was reading faster than actual, My understanding it is quite common for a stock setup to read faster than actual mph on alot of older vehicles.
