How many miles before need to replace tires on Prius v?

45K miles is very good for original equipment tires.

 

you really have to go by tread depth, everyone gets different life span. if you put a penny in the tread, you shouldn't be able to see the top of lincolns head.

 

It really depends on many factors, Tire Pressure, average speed, cornering, temperature. The most controllable is tire pressure, keep them up, I keep mine at 55lbs and put more air in when the TP sensor goes off, at about 40. Don't listen to tire clerks, or Toyota clerks. For some strange reason they all push the same line. They are told to. They sell tires. Use your own judgement, that always works best.

 

Rule of thumb is replace tires based on tread depth and wear.

You can use a penny, a quarter or buy a tread depth indicator tool.- You can look with your eyes.

If you got 40,000 miles or more on OEM tires, they are probably due for replacement.

I only have 20,000 on mine, and I doubt I'll make it to 30,000.

 

My 2012 factory Bridgestones went 105,000 miles with factory door jam pressures. They were rotated at 5k intervals for the first 40k and then 10k intervals after.

 

I was able to get almost 75K out my factory OEM. I did keep them rotated every 5K miles though.

What are your tires: manufacturer and specific model?

Get a tread depth gauge and check them for yourself? They're about 4~5 dollars, at an automotive supply store.

When to replace your tires depends on a lot of things; how low you want to let your tread depth go, mainly. Legally you can drive 'em 'till they're down to 2/32" remaining tread depth. Personally, if they were down to 5/32" I'd be at least window shopping.

Tire age is a factor too. For example, we purchased in Nov 2010, but our vehicle was manufactured Aug 2009, and it's tires were manufactured in the 5th week of 2009. So right now they're well over 6 years old. Our car is low mileage, garage stored, out of the sun for the most, so I can stretch it some. But I can see micro-cracking start to happen, am monitoring it. Tires do age, the rubber harden, start to crack. 6~8 years is considered the lifespan. Google how to read your tire's age.

Ours are Michelin Pilot HX MXM4 215/45R17 fyi.

 

OP: Tyre wear depends a lot on how you drive, how well you maintain the tyres through pressure and alignment, and road conditions in your area. It is a YMMV, similar in many ways to fuel economy.

Replace your tyres when the sidewalls are markedly cracked or less than 2 mm of tread remains. Modern tyres have wear markers in the deep grooves: when the marker is flush with the surface of the tyre it is time (or past time) to change. If you want better traction in snow or rain then consider replacing earlier than the above allows.

 

what made you switch to 10k?

 

Because the free Toyota Care rotations ended.

 

and still went 105k, amazing.

 

I have 83,500 miles on my OEM tires and I should get 90k or 95k without them wearing too thin on tread. I keep them at 42 psi, front and rear.

 

In addition to the factors others have cited, it also depends on what tires your car came with.

And how you want to handle the trade-off between costs and safety.

On a 2/32 tire, in stopping tests in the wet from 70MPH the new tire would have stopped the car where the worn tire would only have slowed the car to 55MPH!!!! 4/32 would only have slowed the car to 45!!!!

Ask them for exact measurements across the tread depth taken in three places.

 

I got 55k on Yokohama Blu earths, and they got better mileage than the Michelin energy saver A/S I replaced them with.

 

My Michelin energy savers 205 60R16 have lots of tread left. The car is at 105,000 KM and the tires were never used in the winter, I use 215 50R17 wheels for winter (but not recommended for pothole season in Montreal). However the sidewall compound was cracking after only a few years and now at eleven years I see that I am keeping the tires too long.
Just need to figure out a good cheap tire for five years of relatively low mileage.
