One new tire + three old ones?

[Bonehead]

I had to swerve to avoid hitting a car that cut me off and jumped a curb. In addition to dealing with a munched wheel and suspension, the right front tire is being replaced.

I have 26,000 miles on the car, so roughly through half the tread wear.

Any recommendations on whether it's better to have the new tire in the front or the back? And as far as not having a matched set on the same axel, the shop guy recommended inflating the new tire a little less - does this make sense?

Any decent tire store will tell you to get two new tires for that axle, and evaluate the other two for you.

I considered that, but insurance is only covering the one, and I have a $1,000 deductible, so I’m trying to avoid spending any more.

Best advice is keep tyres across an axle same as poss, however, plenty of people don’t bother and I wouldn’t unless a big different in tread depth or they are different brand/type.

makes no difference to transmission etc, it’s road handling is the consideration.

Best tyres should always be on rear.

Makes no sense to under or over inflate a tyre on an axle.

Yep, all under-inflating the one tire is going to do is increase the amount of wear and heat in that tire. That could lead to carcass separation and a blowout. Find a different tire shop. This guy doesn't know what he's talking about. ??

OEM tires? Replace them all. OEM tires are not the same tire as the same nomenclature tire the manufacturer lists for sale- the car manufacturers purchase less expensive tires with less range even though the labels appear the same.

Answer: the tire shop should have shaved down the new tire to match the other 3. Discount Tire / Tire Rack does this all the time. It’s like $25 and saves customers a ton of money.

Call up your local store and they’ll tell you the same thing.

This is the answer.

Just buy one from tire rack shaved.

If you can’t afford to get an extra new one right now, leave it.

Dude, you have AWD. You always have to replace all of the tires simultaneously. Has anyone not told you this?

You don't need to on an EV, The reason this is required on an ICE is there is a transfer case or powertrain unit that transfers the single-engines power to all 4 wheels. In the MME there is no transfer case. The idea of replacing all 4 is to protect something that your EV does not have

The MME essentially is set up like two FWD-like transverse mounted setups only connected by the cars body and controlled by the software. The two drive units even have different axle ratios

I always suggest doing all 4 on an AWD ICE or checking the manual for recommendations. For the MME all 4 tires are still best mainly for traction reasons but you could do both fronts or both rears and not damage anything.

No differentials to damage but the Mach E has traction control. It could make the computer think the car is losing traction when its not. That could end with some strange traction control behavior when you actually need it to avoid an accident. You know Ford is going to void your warranty if they see any funny business going on with your tires.

They can not void your warranty

So you’d recommend taking advice about tire replacement from a tire shop ? ?
