usually how many miles until replacing the tire???

I used to drive bmw and had to replace with about 20k miles.

is it similar with rc 350 f sport??

 

It depends on the Brand, tire rating, how you drive, whether you buy ultra-high performance or standard touring (which I get), where you drive, etc. I have an IS and a pair of Conti DWS might last 35-40K miles, a relative in TX has the same car, same tires, and has to buy new tires at around 18-20K miles. Hope this helps.

 

Coming from a BMW you’re familiar with rear tires needing to be replace more often than fronts due to inability to rotate staggered wheels. That said I agree with previous post that there are a lot of factors that go into how long a set of tires will last. For me personally, I had to get a new set of rear tires after 25K miles. I was running summer tires, Michelin Pilot Super Sports. Mostly freeway with occasional spirited driving.

 

Look at your tread wear indicator and the overall visual health of your tires. If you notice tread is low, time to replace. If you notice stress bubbles, time to replace. Driving style and conditions also play a huge factor in tire life. You should use tire rating and visual conditions to determine when to replace.

 

Every tire has its own UTQG or treadwear rating. So it depends on how far and how aggressive you drive your car.

If you want a really long lasting tire, find one with a high treadwear number. And if you want a very grippy/track tire, then get one with a low treadwear...as it will have a softer compound of rubber and will break traction as easily.

Normal driving is hard to assess as everyone drives differently and in different conditions. But check out this link and watch this video for a little bit better explanation.
