Well I have a 2001 Lexus GS430 with oem wheels and tires. The tires size is 225/55/16 Now here is my question will it make any difference if I was to put on 225/60/16 instead?

Yes, it will be bigger and the correct 60 seires tire would be 205/60/16 but it's narrower. Why do you want to put 60's on anyway??

No real reason. Just curious to see if there would be any change in ride quality thats all. So are you telling me if I do decide to go with a 60 series tire the correct one would be 205/60/16 and not 225/60/16 why?

In order to maintain the overall correct diameter of your tire, the higher the aspect ratio(55 to 60) you need to have narrower(225 to 205) width, otherwise you will have incorrect speed because you tire is either bigger(faster speed) or smaller(slower speed).

This advice is proper in that the 205/60 will most closely maintain the stock running diameter of the 225/55. The 225/60 will run tall. Messing with the tire diameter will make your speedometer and odometer monitor speeds and distances incorrectly. Whatever tire you choose, maintaining the stock running diameter is critical.

The aspect ratio (series) is the percentage of the width of the tire that exists as sidewall. In other words, the 225/55 stock tire is 225mm wide and has a sidewall height of [225*.55]mm. The 60 series will have a sidewall height of [225*.60]mm. Notice these two quantities are about equal [225*.55]~[205*.60].

That being said, you are getting the same sidewall depth cushioning the ride whether you are 225/55, 205/60, or 245/50. Yes, the 205/60 will be marginally more cushiony; but, there are other variables to consider: traction, looks, load rating, etc. The narrower tire will make the car look like it is on four spare tires, and the narrower tires are built to handle less load.

A properly picked new OEM-sized tire will greatly improve the ride quality. Some tire types run smoother or quieter, and new tires ride smoother than those with low tread for sure.

All things considered, I would stick to the OEM 225/55. I would simply seek out a high quality passenger tire that will keep the ride smooth and road noise to a minimum. The 205 will not only not look ride, but it will throw other variables out of balance as well.

Hey thanks alot Blizzy and BB430 you were very helpful. I will stick with my oem size now finding a tire that runs smoother quieter than most is a big problem do you have any suggestions?

What is your current setup? What brand of tire are you running now? What other brands of tires did you have before? Do you need to run winter tire or if that is something you need/need not to consider?

I am very sorry for that. Well i'm running stock 16" with Dunlop Sp Sport A2 225/55/16 and my last set up was Dunlop as well. I am looking to get some all season tires. I just want something quiet smooth confortable dunlop just not doing it for me anymore

Try Michelin MXV4, I am a big Michelin fan, others would tell you Bridgestone 060 or something. They are both great tires and you DO get what you paid for when it comes down to prices. Hope this helps...
