I recently bought a drag pack, 17x10 wheels on a 305/45/17 tire on the back, and on the front I have 18x8 wheels on a 245/45/18 tire… when I install the front ones my service power steering and abs lights turn on.. how can I get rid of this I really like the look of them…

What size tire will work, any suggestions for my 18x8 wheel

SaReNi · 05-28-2022, 10:21 PM

this is a great tire calculator site: https://www.tacomaworld.com/tirecalc

plug in you 17 tire first and then play around with 18's...for example, put in something like 235 40 18 and see how it compares in diameter. this will help you to decide what way to or for example, put in your 18 and try 315 35 17 and see how that compares. you will get a feel for it after awhile and can probably find something more close in diameter. good luck with your search!!!

I have the exact same set up. I use a a 225/55/18 in the front. It's a common size so a lot of options but it is about as small as you can get without going to a skinny and still staying at 28 inches tall.

Red zl one · 05-31-2022, 12:14 AM

Thanks for the info guys, does anybody know how much the difference can be in diameter ? Ik a 225/55/18 will be perfect but can I go with a 235/55/18 ? The tire I want is only that size.. my back tires are 27.8 and if I go with the 235/55/18 they would be 28.2, that would be a 1.3% difference. Would that make my sensors trip ?

When I was running Hoosiers if you hold the button to turn of TC for 5 seconds it turn them all off and you wont get the mil light or the faults.
