Hi guys, I have 09 GS350 AWD and I need staggered summer tires for my 19" R Spec wheels. They are 19x8.5 rear and 19x8 Front.

I know the AWD sits higher then the rear wheel drive GS so there is more wheel well space, so I would like to fit more tire in but not rub with the factory suspension, plus we have horrible streets so I need more rubber to protect me.

Any help would be great with Tire Size, Type & Tire Brand & Model.

I need to get these tires asap also, my factory wheel tires are real low.

 

Well there are a couple things you'll want to keep in mind when looking for tires:

1. The stock tires (225/50/17) have a diameter of 25.858 inches, so you'll want any new tires to have a diameter that is very close to 25.858 so that the speedo remains accurate

2. The diameters of the front tires and rear tires should be as close as possible, otherwise you're risking drivetrain issues. For example, 225/40/19 fronts (D=26.087") and 255/35/19 (D=26.027") wouldn't be a bad setup (rears would only be 0.23% larger than fronts).

Keep in mind that I have a RWD and haven't really done a lot of research on this topic, so there may be other considerations that I'm not aware of

As for tires, it's hard to give a recommendation without a bit more info from you as to price range, priorities (grip/performance vs. comfort/quiet vs. treadlife), etc. Having said that, I would go with Michelin Super Sport or Michelin Pilot Sport 4S since they're the best overall summer tires

Also, this topic has been covered a few times before on this forum, so for a lot more info try using the search function!

 

I do not recommend a staggered setup on an awd system unless it came from factory and is tuned for that specific option. I can beat this topic to specifics but I'll stop there; from your post, it sounds like maybe you've ran this setup before seeing this is a summer set and you have been switching to and from winter sets.

To add to Sodium's second reference.. this is the sole purpose staggered setups have a smaller aspect ratio in the rear tires to account for the difference in tire size. Even with a staggered setup on a rwd car, you want to ratio to remain the same or close to it as possible. Now when you talk about awd, this does not apply and many other factors such as tire width, contact patch, rotational force, etc makes a huge difference when you go from a 225 to 255 on an awd that is tuned for a square setup. Like before, I can beat the topic to death but will stop there. The internet is huge and there are tons of info on this and has been beaten to death before.

As for as the tire itself and to make a recommendation, it all depends on the info you can provide us as asked by Sodium. The Michelin Super Sports are actually getting discontinued and the 4S will be the actual replacement to it. Great tire along with the Continental DWS06, DW, Pirelli PZERO, Hankook evo2 (very popular among staggered mid rang tires) etc.

 

Staggered AWD is no issue aslong as you keep the height as Sodium stated the same front and back. Also keeping the height to oem tire is prefered, so incase you get a flat tire you can use your spare tire.

Ive had a flat tire on my old 20" staggered setup and my spare was much smaller then the other tires. When I used the spare AWD flash warnings popped up. But thankfully it did no damage to the AWD system, I was also driving very slow for about almost 1 hr of driving. My current setup I matched the height of OEM to avoid that headache.

 

Here is a good calculator to measure out tires. I would also verify with the manufactor website for technical spec sheet on the tire before you buy it, as many tire companies are not accurate when it comes to their sizing.

225/50/17 are stock awd tires

Ok these were factory R Spec wheels that came off a 2014 Hyundai Genesis. I had them on my 1998 Lexus GS400 with front 225/40/19 and rear 245/40/19 but I had adjustable coilovers and I lifted the car to clear the size. The tire Calculator was somewhat helpful but with it being staggered, AWD, and what height they need to clear so they don't rub its hard.

Any exact tire suggestions you guys suggest to be safe with everything?

I would like to keep 40's because of the bad roads here but I'm afraid of rubbbng, but the AWD does sit higher.

I feel 35's are like rubber bands and you could feel everything on the roads and there's a chance of damaging wheels with so little rubber and all the potholes and bad roads out here.

 

Personally I would try the wheels on now if you have them and see if they rub or not and if they trigger the AWD system. But I dont you will have rubbing issues depending on your wheels offset.

But to help you with the sizing
stock diameter is 25.9"

Your front 225/40/19 are 26.1"
Your rear 245/40/19 are 26.7"

Your front you should be ok with but the rear tires may not make the AWD system up as theres a difference of .6"

Personally if I were to buy tires I would leave the fronts at 225/40/19 26.1" and run a 255/35/19 26" in the rear. that 255/35 has the same sidewall height as the front but a wider tire.

 

Yeah I had the wheels powder coated because they were rough, and since I had coilovers on the last car I would get tires to wear unevenly, even though my car was aligned to specification, so my original tires are gone now.

So 225/40/19 Front and 255/35/19 Rear, ok. Any tire brand & model you suggest? And all season or summer? I think I'll put my factories on in the winter.

Also do Hyundai tires sensors work with Lexus, if not which sensors work with a 09 GS? I've never had a car with tire sensors before so I don't think I want to get a message with these wheels.

 

Tires depend on your budget! The best are usually michelons/pirelli average are hankooks/conti/nitto

the sportier tires will make more noise and not last aslong as say a regular all season. I run michelin primacy and i love them. Ive had conti DWS and had bad tire wear from them

Tire sensors youll need to run your old sensors off your old wheels. Unmount your tire and remove the valve stem and put them into the hyundai wheels. Any tire shop will do this for you.

Tire wear can happen for many reasons if you have a lot of miles on your car then I would replace some bushings

 

If you're going to be running a set of winter tires on your factory wheels, you should get summer tires on your 19s. As for brand/model, we can't give you a recommendation without knowing what you're looking for in a tire and what your budget is. Try going to tirerack.com and reading customer reviews of some summer tires to at least come up with a shortlist

As for whether Hyundai TPMS sensors will work, take one of them off of the wheel and see who the supplier is – if it's Denso, they may work, otherwise they probably won't.

The Lexus TPMS part number is 42607-33021, you can get them on amazon

 

Ok, I bought a set of 4 used OEM TPMS sensors and The new Michelin Pilot Sport 4S tires in the suggested size.

I also need Lexus Center Caps for my Hyundai Genesis R Spec Wheels that I had powder coated Bronze.

Anyone know where to get custom ones made and how to determine what style and size fit the wheels?

 

Good choice on the tires! How old are the used TPMS sensors you got?

As for custom center caps, see if the stock Lexus ones fit or nearly fit, and if so you could just buy an extra set and have them customized. If they don't fit, bring the Hyundai ones to a machine/metal fabrication shop and see if they can fabricate some for you with the same dimensions

 

The TPMS sensors are from the famous auction site and the seller has sold over 1,400 of just sets and more single and they come with new gaskets and locks and have been tested.

As far as center caps, i guess for checking size I could try my factories but my wheels are Bronze so I would need a black background and an L in bronze to match the wheels which would be hard if I could find a place that makes them.

So my wheels have 62mm center caps? If so thanks, I'm going to get the Black and Chrome for now. My car still has chrome exhaust tips and window molding. Besides that, I did hydrographic to the rest.
