Rims are 18" and tires are 225/35/18. Will those look funny and leave a big gap or should I just stick with them. If not, what tire size would be best?

Wow can't spell, go with. Not got. oops.

My stock tire size is 205/65/15. If I stick with my tires it says my speedometer reading will be 5.1% to fast. If I get 225/40/18 tires then the speedometer will be 1.6% to fast. So is it worth buying different tires?

I don't know what your stock rims and tire height is but for my 94 ES300 its 205/65/15. You should try and get closest to the wheel height so that it doesn't adversely affect your odometer.

For 205/65/15 the closest match is 215/50/17.

You can check the recommended wheel using this tire calculator.

I use 225/40/18's and they seem to fit very well. I think its a close to stock height as you can get with 18's

Use the tire calculator link to get as close to stock as possible with 18's.

For my vehicle, stock is 205/65/15 and closest is 215/50/17. If I want 18's then closes is 215/45/18.
