Probably going to have the alloys refurbished this summer and I'd hate to kurb them. Was thinking of fitting one size wider tyre so it overlaps the rim slightly creating a curbing rim. Anyone have any positive/negative views on this?
General wider tyres?

You can get rim protectors or tyres with them built in?

Michelin Cross Climate tyres are excellent and have rim protection. I don't think it's a good idea to fit incorrectly sized tyres.
Most good tyres places would just refuse to fit tyre's that don't fit the rim correctly

There's a bandwidth, tyres will fit on various rim widths, or vice versa. So that should be possible within the required specs. However, the tyre size may not be legal for the car, so there's an issue
Wider tyres (one size) will be okay.
But you need to make sure you keep the rolling radius of the tyre the same (or at least within 5%) or you might get fouling problems. And badly oversized tyres look a bit pony
.
So if you have 175/65 you can go to 185/60 for example.
But even a bigger tyre might not prevent kerbing, especially since the aspect ratio is reducing. The only way you would get much protection is if the tyre is significantly wider than the original (so it's on the limit of being too wide for the rim).
The easiest/best if not exactly the cheapest way to do it is to buy tyres with a built in rim-protector. Otherwise just park further away from the kerb. I never heard of anyone ever getting a medal for parking precisely 20mm from the kerb. Give yourself 20cm instead.

If you do almost anything to your car which moves it away from the standard spec, in any way, you would be well advised to notify your insurance company. Many times you will find it makes no difference to your premium, but if you don't tell them you may well find yourself "out in the cold" when you go to make a claim!
To be fair, I can understand where Dennis is coming from. When I was a lad I could park my old beast precisely 5cm from the kerb and straighter than a very straight thing from planet Straight... but once it's dark, or wet or you're in a hurry you only have to get it wrong once or twice and your shiny wheels are scraped.
These days I give it a bit more clearance (not least because in The Land that Time Forgot, cyclists ride on the pavement and fang your mirrors and paintwork with their knees, elbows, pedals etc. I tried shooting a couple and throwing their corpses into the river but others soon come along to take their place) so parking further from the kerb makes sense.
Cars driving past seem to take more care but I guess sooner or later any car parked on the street is going to get a scrape. But, as above, very wide tyres that deform slightly on the rim is less of a good idea than tyres with rim protectors. My sister's Megane has always had them and her wheels (bearing in mind they're 20 years old) look like new still.

Yes, very easy to make a small mistake and rub a kerb. The lower the tyre profile, the easier it is to scrape the wheel. And to be honest, in my experience even tyres with rim protection will only protect against the lightest "kiss".

To avoid scraping your wheels, you have to curb your enthusiasm for getting close to the kerb!
Bridgestone turanza, and potenza fitted to both my golf and Countryman both have kerb protection built in and can be very reasonably priced.

There is an online calculator you can use to work out what profile wiil allow you to fit wider tyres yet keep the ABS, spedometer and auto-box (should you have one) happy. My car's factory fit summer tyres are 115x65x16 but 135x60x16 circumferential difference is 0.01
