Is it Really Necessary to change both tyres after 1 is punctured?

So experienced a puncture this morning ..Which always sucks , luckily was 5km from a fitment place.. My initial plan was to just use one of those plugs as thread is still around 75% .. Guy insists I replace both front tyres and I ask him to remove tyre 1st to assess damage .. Puncture very evident on inner sidewall so that plan was epic fail..

So I eventually request that he just replace the damaged tyre with new one , he could not source the OEM brand and recommended an alternative with 2 year pot hole warranty ..I agree.. 3.4k later he then gets me to sign a waiver on job card that I insisted only 1 tyre be replaced!!!

Am I missing something and is it really necessary to replace both tyres if thread on other tyre is still good ? Or was he trying to shaft me ?

Tyres are 19inch non run flat

Look it occurs (sometimes) that the very people that are in the trade are idiots that don't know what they are talking about or do stupid things. It is unfortunate but a possibility that this guy was trying to sell you a second tyre.

While I am not expert, I would say one tyre replacement is fine as the tread is 75% on the other one. What he should of suggested is to move the uneven tyes to the running wheels if your car isn't 4x4 with the same tyres on the driving (powered wheels).

Perhaps take it to another place for a second opinion.

This neck of woods we often get crap by the cops if the tyres on the same axle are not exactly the same brand and model... not sure if there is an actual law, but that's not the question I wanted to ask after he gives me a free pass

Be glad its just 2, on my car, i need to replace all 4
What the in the duck are you driving? Bugatti?

As for replacing both tyres, the problem is that if the car sits at an angle because one tyre has 75% wear and the other has 100%, it leads to aqua planing. He’s not wrong per say but if the tyre is 90% then it’s not required.

As for having 2 of the same types of tyres on the same axle, that isn’t really required so long as both can dissipate water effectively.

I’d get 2 tyres and keep the other one as a spare.

I hate the way you go in for tyres and they try sell you a ton of new suspension units and other crap. Fuck off. I know what you’re trying to do.

Sounds like a dodgy story to me. That's exactly what a diff is there for (cater for different rolling speeds between wheels both left and right and in your case front and back).

Based on advise from @JollyJamma best place to get a good deal for tyres in Jhb ? I know Minty's back in day offered great deals...Also its ironic most of "major" firment places dont keep stock and make you wait for an hour to have tyres delivered from their suppliers ... As for Branded tyres seems to becoming a special order item as most of the run of mill franchises offer better deals on "no name brands" but claim they come from same factory .. Any truth to that?

I would also agree with this. The diff is tough in Subs, it has to be to last a life time. You'd put 1000000% more strain on a diff going up a tough pass to get to your holiday house than a wheel that's out by a few mm.

If you are in Cape Town and need good tyre prices, call I.E Tyre Distributors 021 934 8154. Generally, they have very good prices.

Most diffs won't cater for constant difference in wheel diameter.

On some cars, if there is enough difference in tyre circumference, it could have a big effect on stability control/ABS and in some cases tyre pressure monitoring (some types work by averaging rolling distance to estimate tyre circumference). And when you replace tyres, there is a chance that a different brand will have enough of a difference in diameter to impact this (even if the specs are the same).

I presume that this car has run flats, given the price? In that case it would have given an ABS-type error if there were a problem. If not, I would not worry too much.

Apparently you shouldn't use tires that are over 8 years old even if the thread is 100%.
They have expiry dates.

NEWS TO ME

So becarefull when you buy new tyres. Sometimes they sell you 7 year old tires that have 100% Thread and you find yourself having to replace them the next year..... #robbed

Quite correct. Yes tires actually have a 5Y shelf life, it's not so much that they expire but the compound from which it's manufactured loses it's elasticity which means you'll get faster than normal treadware

Any tyre above 5Y old will suffer from
Belt Ware
Steelthread Rust

If you're sold a tyre older than 5Y it's generally considered a 2nd Hand tire and shouldn't have any warranty on the unit sold.
