Hey everyone, has anyone adjusted their tire size using Forscan? I know it's in the master spreadsheet and I recall seeing it in the options to pick your tire size but i also know manually changing the values vs the as-built easy method can work better at times. Just wondering if anyone has tried either and which method you used successfully. The forscan sheet claims this adjustment will compensate the Speedo accordingly so just trying to get the tires/speedo to match if I alter the size a bit, even if it's only off by a less than 2% uncorrected, just seems like a good idea if I can keep them aligned.
Also before anyone warns me about staying in the accepted variance, which I see on just about every tire/wheel thread here, I'm looking at tires within the normal accepted range of a few %, but considering just a little more sidewall and it opens up a few more tire options and in some cases lower prices. I noticed that comparing the PIU profile to the regular explorers it looked like the 18" tires on the XLT were a little bit bigger profile at 245/60/18 vs 245/55/18 and also the Sport's 20" tires too at 255/50/20. I'm also moving to 19x8.5 wheels, so probably jumping to a 255, so I know if I pick a size tire that isn't equal to one of the stock tires, that I will for sure have to use the manual entry part of Forscan to enter the correct value.
