I recently put 31/10.50/15 tires on my '99 toyota tacoma. These are bigger than the original size that came on the truck. Do I need to have to make any adjustments to the computer to adjust for the larger size?

no no, it should be fine. My cousin put 39.5/14.5 tires on his truck and everything was still the same. You should be fine, don't worry about it.

the computer will be fine and your fuel mapping will change accordingly..you might lose a little power..what gears came on your 99?

the only thing that will be different is your speedo might be a bit off...

i had 31' on my truck when i bought it...now i have 32's...the puter is off by about 1-2 mph...not a big deal....
