I have a 2021 is350 F sport and my tires wear very fast. I already got some figs LCA bushings and that helped the inner tire wear, but I still go through a set of michelin pilot sport 4 all seasons a year even with rotating them every 5,000 miles. I do drive hard and like to have fun on the backroads, and I know that kind of driving wears them out faster. Should it be that fast I put 12,000 miles on them and they are at 6/32?
Thank you for your time I appreciate it

 

You are buying a soft sport tire with 300 thread wear. IS are notorious for fast tire wear, aggressive driving isn’t going to help prolong the tire life either. Buy harder compound tires if you want longer lasting.

 

Thank you I appreciate it! Do you recommend a harder compound tire or just bite the bullet and keep the better grip with the softer one and pay more?

 

That is a question only you can answer.
You know you have to pay to play.

 

6/32" after 12,000 miles isn't bad at all for this car, especially for a high-performance all-season tire.

I have Continental ExtremeContact Sport 02 tires on my IS 500, and after about 7,000 miles, I'm down from 10/32" when they were brand-new to about 7/32" now. So that's what you could expect if you were to go for an even higher-performance tire.

My former IS 350 was much the same. It chewed through the original Bridgestones on the front axle in under 15,000 miles.

FWIW, when my tires get below 5/32", I start tire-shopping.

 

I am at almost 18,000 miles on my 23' IS 350 and I am starting to tire shop. I semi knew about the inner tire wear and the fact that these can go through tires quickly. Since I mostly just commute and what not with my IS, I am going to go for a harder compound this time vs the stock. I rarely do any hard or spirited driving.

 

My car came with new or fairly new mismatched all season 300 and 320 thread wear tires that I don’t recognize the brand. Rear are holding up good but the front are showing the typical inner wear. I did install RR Racing lower control bushings about 2 months into my ownership but I never got the toe in align to zero. When I replace the tires I will get Continental dws 560 threadwear and will have the toe in adjusted to zero.

 

When you replace the bushings, is an alignment required? Sorry, just started researching this issue. Thanks!

 

I believe it is recommended since it can change the toe and what not after installation.

 

Also with a 2023 F-Sport and the original Bridgestone Potenzas are a little more than half way done at 19k miles. I'll give it another 5-6k miles and start over with new Michelin all-seasons. I think that's pretty fair overall for the stock sport tire, but I do drive like a grandpa. For comparison, I got 35k out of the original Bridgestone Turanzas on my 2020 F-Sport V6. That was pretty amazing! All stock and no uneven wear on any of the above.

 

I did not take my car for realignment because steering didn’t appear to need it. But others have stated that zero toe is necessary to really correct the inner tire wear. The bushings significantly slowed down the inner tire wear, they are 100% worth it.

 

If I can feel the problem with my alignment, my experience has led me to believe that it's a severe alignment issue. Sometimes you cannot feel anything out of the ordinary.

 

My car alignment was not negatively affected by the installation of the RR Racing bushings, the inner tire wear is very even on both sides, car drives as straight as an arrow without having my hands on the steering wheel. It is more precise due to the fact the aftermarket bushings cut down on the excessive squatting the original bushings promote. Based on my experience with my Subarus over the years, they required departing from original setup to eliminate uneven tire wear. There is no front camber adjustment bolts on the IS, the toe adjustment according to other people here is necessary to correct the remaining inner tire wear. I trust that information others have documented and will be taking my car to a good alignment shot I’ve dealt with before for my Subarus. The Subarus would excessively wear the outside edge of the front tires on the factory alignment. The trick to perfect even tire wear was 1 1/4* negative camber and zero toe. Makes sense zero toe will also help on the IS. I’ve been wanting Continental dws since I purchased the car, the [moderator edit: removed due to derogatory/incorrect term] tires irritate me but I’m also frugal so I need to see the tires wear in order to justify replacement. I do keep a religious eye on my tire inflation and keep it at the recommended 36psi cold. I consider the inner tire wear very moderate or minimal at this point after the aftermarket bushing installation. The tires are only 320 threadwear, Continental are 560 thread wear, much harder compound. But looking on Tire Rack now I think I’ll go for Pirelli all season that are 500 thread wear. Reality is I might be able to keep the Chinese tires on thru the winter, specially if I go get that zero toe alignment. I will post a print out foto showing the new alignment specs.
