Hi,

I would like some wheels for a Lexus GS but I'm still not sure about the size; I'm thinking about 20 or 21 inches. Do you have any info about 21"s for a GS? I haven't seen any yet, thanks for any information..

 

It seems 20" is the norm for aftermarket. If you want a rouher ride.. 21+ will do that for ya

Check out the "tires and wheels" threads

 

If you want to lower the vehicle and put 21's on you would need tiny tires, so you wouldn't rub.

 

thats exactly what I was thinking! I believe in my opinion the GS will look so good on 21wheels rather than the 20. even if you drop it. it won't affect the ride at all. I really wanna see someone tries it

 

I think I'm going to give it a shot next spring.

 

Lets first address the ride quality ride difference between 20" and 21" wheels. Unless you've had a vehicle that's had both sizes then I don't believe that you're qualified to simply say "if you want a rougher ride go with the 21". Actually the overall diameter of the SIDEWALL of the tires are very close to heing the be same thickness. Anyway I have an F-sport that's LOWERED and currently have TSW Nurburgring 21x9", 10.5" wheels and Pirelli 35/30 series tires. Rides exactly the same as it did when I had Lexani Forged 20" wheels on them. They were/are staggered with no rubbing either. 245/35r20 (21), 285/30r20 (21) tires. Most are running 20" because they're a few more wheels to choose from (unless its a 2 or 3pc forged wheel), and the cost difference could be pretty substantial. I will posting pictures of the vehicle within the next week. Cars in the (performance) shop checking on building a custom manifold for a single turbo setup.

 

Looking forward to seeing your build.

 

If there is no difference in sidewall, why bother going with the bigger wheels?

You are making assumptions on why people are going for 20's, by the way. There are many that hold the belief that sidewall height relates to ride... IJS

 

I NEVER said there's no difference in sidewall. That's ridiculous. To answer your first question, the reason we all go to larger wheels is to maximize the performance of the vehicles handling by lowering the side-roll of the tire. That only being achieved by using a larger diameter wheel, and a lower profile tire. Now let's address the difference between 20" and 21" on this (or MY) 4th gen GS350. My suggestion first of all on MOST going with 20" vs. let's say a 21" is like I said before, more options in 20", and less out of pocket expense. This exclude anyone willing to special order multi-piece offerings. Now addressing your other statement. You're correct in that sidewall does translate into more driving comfort. If you CAREFULLY read my post it'll explain in detail that I chose to go with 35 series fronts, and 30 series rears. I too feel like you do regarding comfort. I could have basically achieved the same overall diameter of a 20" wheel by using 30 series fronts, and 25 series rears. But I chose to sacrifice some handling performance for comfort and less possible damage to the wheels from bad roads and debris. I've been in the motoring field for 20+ years. From a tire tech to management to even ownership. There's not to much I don't know about this subject. Currently I can be reached at Butler Tire Co. (Austell GA.) most days if you'd like to further this conversation. I handle projects such as this most everyday that extend up to the some of the most luxurious or performance type vehicles that on the road today. Ones that can not tolerate any type of mistake. Visit the gallery if you will at butlertire.com to get an idea. Some wild and some mild, but all done professionally. Thanks

 

Wheels and tires have arrived.

 

The wheels

 

Can't wait to see it

 

Sweet, can't wait to see it on.

 

Those look amazing. Can't wait to see the finished product.

 

Just a couple of shots. I really wanna wait until next week when it's finished being lowered and the chrome painted. Then on to the real mods........
