Morning,
I’m unable to advise on whether or not your suggested tyre size provides any benefits present problems as I’ve never tried them myself and you’ve not mentioned the wheel width are you intending to fit them to.
What I can do for you though is share the link to the Definitive Wheel and Tyre Thread as you should be able to answer this for yourself once you w studied it.
Hopefully someone will be along who has actually tried this size to give you their verdict.
Kind regards,
Tom

Hi Tom,
Apologies. I am on standard 15" rims. So the width is as per standard, just a little extra sidewall. I did have a look on that guide first, which is very useful. But that particular size is not in the list.
Thanks,
Martin.

Hi Martin,
Tyres size recommendations certainly aren’t my area of expertise sorry. As you’ve already seen the linked thread and cannot find your size mentioned I can only but guess they are either:
1. Are not recommended due to rubbing
2. Are not recommended due to providing incorrect Speedo reading
I did notice a member mention this exact thre size at Post #9 but this was only for winter tyres.
Personally I’d only use the sizes on the thread as it’s been complied and adjusted over time with input from this great community. If the tyre size isn’t on the list then I personally wouldn’t fit it unless someone can vouch for this size.
Let’s see if anyone else can jump in who knows a bit more about the size you mention.
Kind regards,
Tom

It may not be in the tyre thread but I think I’ve seen reports of 175/65/15 being used with success by other members - by which I mean they didn’t rub and the speedo became more accurate as they over-read as standard.
Worth a try if you really want the tyres and they’re a good price AND you Google the exact size with A2OC as a search term and confirm my recollection.

They should be absolutely fine as long as you are on standard, not significantly lowered suspension and it is in good, not dilapidated condition.
They will improve the comfort, ride quality and bump absorption of your car and you will also find your speedo is more accurate, over reading between 1-2 mph instead of the usual 3-4 mph with standard factory size tyres fitted, ie when your deeds reads 70 mph you will be actually travelling 68+ mph instead of the usual 66 mph.
Below are a few photos of a 175/65 15 tyre fitted to a 6j (6" wide) Pepperpot wheel where as your standard A2 15" alloys are a 1/2" narrower at 5.5j which will make the fit even better still.
Hope that helps ?

One other thing I should probably have mentioned is the larger overall rolling circumference of the tyres will raise the gearing slightly too, meaning that when pulling away it might feel fractionally slower but the up side of that is because the revs will be lowered slightly, at motorway speeds the engine noise will also be reduced slightly too ?

The next size up on the sidewall over standard is normally fine. I run 185/55x16 instead of 185/50 for example, so I wouldn't expect 175/65x15 to give you any problems. I've previously had 185/65 on 15" pepperpots, those sidewalls were even larger than 175/65 because it's a ratio of the width. Although they were visibly oversized they didn't rub, and they're still in use on another member's car right now.
You won't tell from the speedo that you're going any faster - the same number of wheel revolutions per minute will produce the same speedo reading as before, it's just that each revolution will be taking you that little bit further. The difference will be in the speed your GPS says you're going for a given speedo or rev counter reading, compared to before.

I always used 175/65 on the standard 15" wheels as they made the speedo read pretty much spot on.
Now I use 185/65 on Pepperpots because they are slightly wider, as mentioned above. These do make the speedo "even more accurate", borderline under-reading so you have to be careful, but the comfort is definitely improved and in conjuction with the 6 speed box makes motorways far more relaxed.

I have 15" wheels with 195/60 tyres and have no rubbing issues. My speedo under reads by 1 mph.
https://www.tyresave.co.uk/tyre-size-calculator/
is a useful site for comparisons.
When I fill in 175/65 vs 195/60, I get 23.96" (175/65) vs 24.21" (195/60) diameter.

Under reads? So when your speedo says 70, you're actually travelling 71mph?
I've never known an A2 speedo to under read before, didn't think it was possible or do you mean it over reads by 1mph?

One of my cars is on 185/65 R15s, the ride is marginally better than on 185/60 R15, better grip in recent snow and according to TomTom the speedo is now spot on. No problem with rubbing. I’d recommend them

On one of ours we have 175/65-15, on 6" wide Audi rims. Works fine even though they are studded winter tyres.
You have 6Jx15 ET37 rims (number 3 in the chart below), which are better suited to 185 and 195 size tyres than 175 size tyres.
185/55R15, 185/60R15, and 185/65R15, 195/55R15, and 195/60R15 would all work well with the 6J rims.

Most A2s sold in the UK that left the factory with 15" wheels, came with the alloy rim numbered 1 in the chart above.
You can see from the chart below that these had a specification of 5.5Jx15 ET34. They are known to be lightweight as they are made out of forged aluminium rather than the more common and cheaper cast aluminium.

I presume you must have clicked on the op's avatar to determine that he is running the optional SE 15" wheels (which are indeed 6j) rather than the 'standard wheels' that he stated he had in post #3 which are 5.5j and I took what he said as correct when I replied.You have 6Jx15 ET37 rims (number 3 in the chart below), which are better suited to 185 and 195 size tyres than 175 size tyres.
185/55R15, 185/60R15, and 185/65R15, 195/55R15, and 195/60R15 would all work well with the 6J rims.

Both sets of wheels however, were supplied fitted with the same 175/60 15 tyres from new and I actually have a set of each ?
