I've recently picked up a used car.

I noticed it was leaking air badly out of one of the alloy wheels. On inspection there was a large dent in the inner rim.
I found an alloy wheel repair specialist in my area. They charge £50 to remove dents.

Whilst dent was being removed they also discovered a crack. So £50 to remove the dent & £50 to weld the crack.

The crack has been welded thoroughly but the repairer didn't grind down the welds.

Will this be an MOT fail?
I'd like to think not as this same place also does MOT repairs but section 5.2.2 of the manual states this as reason for a failure

"(a) Any fracture or welding defect on a wheel"

I'm not sure if this means any welding, or just defective welding.

Can anyone with experience in doing MOTs or having wheels repaired with weld showing who've had an MOT done recently confirm?

I've got welds on both rear wheels of my Jag... the 20" wheels crack for fun.

They're not ground down - the (different) people who welded mine both said the same thing: that they don't do so as it weakens the weld.

My garage actually mentioned the welds as an advisory on my last MOT, but they are incredibly finicky about such things (one of the reasons I use them - they are very thorough), and I've had MOTs before that have not mentioned it. My understanding, therefore, is that the reason for failure is a welding defect.

Welded wheels are fine.

Poorly welded wheels will fail.

Whether you want to run welded wheels is another matter...

Every steel wheel has welds on it.


The MOT should failed defective welding. Not 'welding'.

Didn’t realise they left the welds intact as that must be a bd to balance!

They do, but they're machine welded and inspected, by companies that have to stand behind their product if it goes wrong.

I do not fail wheels that have been welded to a decent standard although I do advise them. A tester up the road from me does fail them though, he thinks a welded rim is defective.

I bought a car with a welded wheel and it was never an issue on any MOT, before my ownership or during.
