Got a great deal on rims and winter tires, but 1 tire is damaged and can't be repaired. 70%+ remaining on the other 3 tires, and I've ordered a new replacement for the damaged tire. On a G37x sedan, does it matter if the new tire goes on the front or the back?

 

I'd put em on the front =]

 

New tire goes on the back, keep the fronts matched.

 

Newest tires should always be put on the rear of the vehicle. (assuming you're using the same size all around)

good to know.... thanks.

 

Thanks for the advice, I'll put it on the back.

 

70% of what? 70% of 10/32nds? 70% of the 8/32nds before you reach your wearbars? 70% of the 5/32nds wear before winter tires reach a somewhat reduced functionality?

The general recommendation with an AWD is any more than 2/32nds tread difference you should either replace them all, or shave the new tire down.

I know not everyone buys into it, but 2/32nds is a pretty significant difference in tire rotation when you consider the mileage lifespan of a tire.

 

70% of 10/32 - I was worried about that too, and then found out that the new tire was on 45 day back order. I picked up some near new Blizzak LM-25s and have them on the car now. I'm very happy with them on packed snow and ice, haven't had deep snow yet.
The new rims had TPMS sensors already installed, and so far no TPMS warning light! Maybe 2010s only need to see 4 sensors, not just the original sensors?

 

Crap...took 4 days, now the TPMS light is on. Hope 1 of the sensors didn't poop out.

 

Nah...I'd guess you're alright. I did the same thing before, put 19inch Infiniti sport coupe rims on my sedan. Thought I was good, few days later the light came on. No idea why it took so long. They just need to be programmed...
