I have '00 GS300 and a '98 LS400. What are the widest tires I can put on these cars that don't whack out my speedometer reading too much?

Search, we've discussed this in detail. What size rim?

stock 16" on both.

I'd stay with the OE tire size if you're not going to coin-up for new wheels- Lexus already undersizes their wheels for the OE tires, anything wider looks very "bulged" on the rim.

Also, if you significantly undersize the rim width, a wider tire may actually decrease handling performance, as the tire will tend to 'squirm' on the wheel (particularly while imparting cornering loads) more than the OE tires.

I agree, wider is not always better. Especially in bad weather.

C'mon. I ain't trying to be a freak. I just wanted to know how much wider of tire can i put on my cars with the stock wheels and it still look good and not rub. 20 more mm? 30 more mm?

From what I can tell, it seems I will be better off just staying with stock size tires.

I have always thought the stock tires looked good. In addition, they are mostly high quality IMO.
