I am looking at a used 2017 IS 350 AWD and looking at the carfax it looks like the tires are being replaced every 8 to 10k miles along with alignments. Doing some research, it looks like the 2017 had a common issue with uneven inner tire wear. I am curious if that was something fixed in a later year or still a common issue?

 

common issue its the stagger setup the cars has , my front inner tires would do the same, Im not too sure about 7-10k mileage changes but it would depend on the way you drive

 

Is there a fix? I saw some threads on replacing the bushings with rc-f or poly

 

Probably the most single discussed thread on this forum. Search “RCF GSF BUSHINGS” and you’ll find dozens of threads. Many install the RCF/GSF bushings or aftermarket poly bushings. I installed the RCF/GSF on my 350 awd and front tire wear is basically completely gone + car handles better.

 

This is incorrect, the front tires experience inner tire wear due to the soft LCA bushings that come stock on the 3IS. As stated above though, the RC-F/GS-F bushings pretty much eliminate that issue for most. Of course for us RWD, our rear tires wear out much faster than our fronts due to the power being sent to the rear wheels.

 

Thank you everyone for the responses. Will I still have issues with rear tires even if I fix the front bushings? It is AWD.

 

The front bushing will only solve your front tire inner wear. I don't have my IS anymore but the two I had, none of them had rear tire wear, was mostly the front.

 

Well I don't really know if the used car has front and rear problem. My concern was when I looked at a carfax for the used car it shows Tire(s) replaced at 8,000 miles, 15,000 miles, and 22k miles. The used car lot also replaced the tires at 32k miles. So I am not sure if they are replacing just the fronts, if they have really bad luck, if it is one tire at a time, etc.

 

If I had to guess, I'd say not all four tires were placed each time. Maybe that's obvious, apologies if so.

It's also important to note that driving style plays a big role, as well as what tires went on the car. For instance, I've seen cases in which rear tires get worn down pretty quickly, too, despite the front LCA bushing issue.

If you have other options for your IS, don't get too fixated on this one, if the tire issue is concerning to you. Then again, this could have been a case where they replaced fronts, then rears, and finally fronts again, which would be totally normal.


edit: Here's an idea. Make the used car dealership work for you. Ask them to get the service history, or call the shop/dealer that changed the tires and ask which tires were replaced.
