New tyre size recommendations std wheels

[Dstan0710]

Hi guys I’m looking for advice as to what size tyre to replace the old cracked tyres on my T25. As of the moment they are on 185/75/14 but don’t really understand tyre sizing.
Is there a better option in terms of size on the same wheels
I’m going to put lower springs on at some point but won’t be soon.
If this has been covered I’m sorry as my searches didn’t flag anything.

If you intend on keeping those wheels, I would stick with that tyre size.

Been struggling to find 185/75/14 locally here in Mid Wales. Can get 185/70/14 and wondering if it would really effect the ratio that much.

Different sizes are possible on std rims, but it will mess with your gearing. Larger sizes probably won't combine well with lowered springs either...

So going smaller with the 70s might be ok. Specially if I lower it one day. Very little over a mile in terms of extra rotation when I went on a calculator app
