Is this tire repairable?

[RMoore]

Returned home from a week away and while driving to work today noticed tire pressure warning with right rear tire pressure at 31 psi compared to the other 3 at 37 (confirmed with gauge). When I got back home from work and looked at the tire I noticed the screw. The pressure did not decrease from 31 psi all day including my 12 mile round trip to and from work. I suspect that this happened sometime before I left for my week-long trip and that this has been a very slow leak that was only picked up when I first drove today. Photo is below--just wondering if there is any scenario (maybe if only a very small hole?) where this might be repairable, recognizing that this close to sidewall makes it unlikely. I will obviously bring it to a tire shop, but wanted to get a quick read here so I can prepare myself (and decide on a replacement).

If it's not repairable I will likely just replace all 4 (currently at 13,500 miles) and would need to decide between Michelin Cross Climate vs Continental DWS06 plus.

I recently plugged a nail hole at a spot very close to yours, but about 1/4" closer to the center. So far so good at 39 PSI. It doesn't hurt to give it a try If I were you.
Here is where it was on mine

No reputable tire shop would repair that.

If the damage is outside of the cord belts (too close to the edge) the structural integrity of the tire is compromised.

Thanks, that was my sense based on prior reading but the link you sent makes it pretty clear.

Had a larger screw in a similar spot in June with about 22,000 miles. Discount Tire recommended replacing all 4 because doing 1 would damage my suspension (not sure if that was bs). I replaced all 4 because I was going to in the fall anyway. Got the continental sport and I like them.

No.

I've had a local shop fix a tire with a similar nail location. The main reason chains don't like to repair these is that being near the edge means the part of the patch will be in an area that flexes a lot, and the patch could come lose and start to leak again.

Reason they don’t “like” repairing tyres there is because it is unsafe, those that do are cowboys, it’s unsafe and in UK it is illegal! A criminal offence, literally!!

Thanks for all the replies, I plan to replace.

the concern is the all-wheel drive is tuned to tolerances in the relative outside circumferences of the tires. since you were at 22k miles you were far enough into the tread life that putting a new one on would be enough to be out-of-spec.

the other option is shaving the replacement tire to match the existing tires. since most shops don't have the equipment to do the shaving on site it adds delay to tire delivery. for most folks, getting the tire fixed "now" is the option they want so you end up with all 4.

Tirerack.com shaves new tire to mach your other three last time I looked. Haven't got it done, don't know how's it done though.

Hear this all the time about rolling circumferences and it’s effect on transmissions.

It’s mainly a load of old cobblers in my view.

Always a good sales pitch!

Road speed in modern cars is calculated from the average sensed wheel speed of all 4 ABS sensors so differences in rolling circumferences causes no problem there.

In terms of this tuning to circumferences, the difference in tyre circumference does affect wheel speeds, slightly.

Think about this logically, though, putting things into some kind of perspective.

What do you think happens when you go around a corner or bend? Any corner or bend, however sharp or gentle which is a very significant time you’re driving.

Inside wheel slows down, outer speeds up.

Front axle takes a slightly different course to rears so all 4 wheels are going a different speed quite a lot of the time.

Never wound up transmissions while ever I have been in the motor trade since 1977 and never will!

Only exception is where diff locks are faulty or are left engaged when vehicles are returned to road after off-roading on soft ground where diff locking is desirable.

Should never drive with diff lock engaged when on road as that will wind up a transmission, differing tyre circumferences will not.

Traditional 4-wheel drive with direct drive as direct as it is from gearbox through transfer boxes to differentials naturally accommodate differing wheel speeds or the roads would be littered with blown up transmissions.

Differentials are so called for good reason - they do what the name suggests.

EV 4-wheel drive is less susceptible to this phantom transmission wind-up further still due to their design.

The reason there is good advice to change tyres at same time is to achieve having tyres of comparable age, inflation pressures, compound, tread depth, pattern, type, brand etc across same axle for consistency of handling on each side of an axle.

Best tyres should always be on rear to minimise risk of loss of control due to oversteer because for most motorists correcting oversteer is counter intuitive so is a dangerous characteristic.

The “shaving” of one new tyre to match another which is worn is a questionable practice and makes no sense from engineering and budgetary points of view.

If concerned about differences in tread depth you should have a nervous breakdown about the effect differing conditions due to aged tyre compounds would have and the effects of the very shaving a new tyre and having tyres with those differences fitted across same axle.

Best advice as far as I’m concerned is if difference in age and tread depth of a new tyre across same axle is so great that is of some concern, change both on same axle.

Is my view.

There’s loads out there but beware which information you believe.
