Message	:I posted this in the tech section, but there's been no response. Emailed Coz as well, but he wasn't sure. Is it possible to change the speed pinion gear so that the speedometer reads correctly with a 45 series tire? Nope. The only pinions that are available are to account for NA and TT gearing. There isn't really anything in between. :I went from stock wheel/tire size to 245/40 and definitely could tell a difference in the ride quality. Speedo was off ~2-3mph as well. With the 45 series tire, it's going to be 5mph off. :Any advice? I'm not sure why you're concerned about 2-3 mph, but your only real option is an adjuster box as lugerz mentioned

(n/m) - SMAZ (OKC) 11:05:39 01/09/12 ... or you drive 5 under what is says on the cluster. (n/m) - Bernie (NoVA) 11:43:36 01/09/12 what if its dark, and a fuse has blown from the trailer - Adam (NoVA) 12:03:27 01/09/12 Worked out fine in the end. (n/m) - Bernie (NoVA) 12:04:27 01/09/12 what if the officer's radar isn't calibrated correctly? - aliaZ 12:14:46 01/09/12 it isn't that simple - aliaZ 12:01:51 01/09/12 not really. the adjustment boxes are better. (n/m) - Antihero 16:14:55 01/09/12 no, that would be retarded - Adam (NoVA) 17:12:41 01/09/12
