95dfwls400 Posted December 8, 2008 Share Posted December 8, 2008 All, I have an opportunity to replace my factory 16 inch wheels on my 95 LS for a set of 18 inch off an RX. Will those wheels fit my car with no modifications? I don't want to alter the ride too much, so how much difference will be in 18" tires with the ratio of /45 or /50??? Thanks for the help.

TA in KC Posted December 9, 2008 Share Posted December 9, 2008 I don't know if they will fit, but they will certainly have an adverse effect on the car's ride. If you want to keep your LS400's smooth ride, stick with 16" wheels. Quote Link to comment Share on other sites More sharing options...

I have 18" after market wheels on my 97 LS 400 with 235-50-18 tires, it looks good but rides rough I can feel every small bumps on the road. Should you decided with after market wheels due to the large front calipers is a challenge to find the t wheels to fit and is expensive.

don corleone Posted December 9, 2008 Share Posted December 9, 2008 i read that car wheels should be used on cars and truck wheels should be used on trucks. something about the construction method and planned tire. i also read that fwd wheels should be used on fwd and rwd on rwd. dont know if this is all true but if you look at lexus wheels on ebay and they have a fitment chart normally there is all cars. but that is ebay...

OP-the RX 18"s will NOT fit on your car as they will not even come close to clearing the big brakes present on the 95+ LS400. a better alternative would be the 06+ GS350/430/460 18" wheels or LS430 18"s as they will clear no problem.

The original poster does not drive an LS 430. His LS 400 came with 16" wheels...what it's suspension was designed for. If the suspension of the LS 400 could handle bigger wheels without an adverse effect on ride quality, I'm sure they would have been offered. The LS 430 is not the same car.

The LS 430 is not the same car. actually, if you'll note, there is no significant difference int he geometry nor construction of the 2LS vs. LS430 suspension. the reason Lexus didn't offer 18"s at that time was because in the 90's wheels >17" were still mostly reserved for high end sports cars and the like. the GS even only got 17s because the production/tire cost was high and required too much retooling.
