Speedo correction with bigger rims??
Guys, usually with changing rims to a larger style from stock you have to
change a gear in your transmission FROM the speedo to get the proper
reading and it's set by the overall tire height. Any deviation in tire height between the old and new one's throws it off.....
I'm thinking of putting 225/45/18's on my '98 ES300
instead of the stock 205/65/15's
Anyone accomplish this and get their speedo reading accurate or did you
guys all just slap the rims on and HOPE that it's still reading accurately??

Alot of members ride 18's with a 40 series tire. I haven't seen any yet with the 45 though. 40 I think is the closest you can get to stock diameter. But jf you get the 45 on there I'd like to see a pic what it looks like. GL

your can figure it out on this cool website.
www.wheelsmaster.com. click on the calculator in the menu bar, then plug in your current size as tire #1 and the size you want to go to as tire #2.
(keep in mind, sometimes their server ain't the best, like today.)
but it is a cool calculator. Give you clearence specs, speedo corrections, acceptibility limits, etc.
