>I just want to check to make sure these will fit, though from what I've been reading they will.

 

>I'm curious as to how much, my Odometer and speedometer are going to be off.

 

Thanks

You're speedo will be off rouhly 2-3MPH slower than traveling speed at 60MPH.

OR

When I drive 1 mile in my Altima my Pathy only shows .9 miles. I know that much.

check out this page as it will give you all the conversions you need. http://www.4lo.com/ I know that with my 98 XE stock tires were 235/75r15 and with 31's my speedo was off ~1.08 mpg. Also try a search theres a lots of post concering this. For example: http://npora.ipbhost.com//index.php?showto...3&hl=speedo hope this helps.

my 89 XE came stock with 31x10.50 on 15x7 rims(3.8 backspace) I never heard anything about the spedo being off in 20 yrs and all the tickets are for 10+ excess of speed limit not 2-3 in excess. I'm lookin to but 32's on it now w/ 15x8 rims and I only have 1" t-bar lift

Thanks, if its just 2-3 mph slower I'm not going to recalibrate it, as I run my stock size, winter tires during the winter.

it is good to know how much you are off though because it will affect your mileage

i figure about 10% faster then showing.. it's actually a bit of a diverging line, not flat. there is a thread somewhere around here (from a while ago) where this was discussed. not sure if i chimed in (probably) but i am almost sure that precise1 is the one who actually posted the table of numbers.

When I got 31's my speedo became correct. Oh well.
