tyre size question

Post by Scottyx » Fri 05 Oct, 2018 6:26 am


I tried looking up the correct tyre size for a 1970 280S.

I came up with 185/80 x 14

Does this sound right? Is it OK to use slightly different size tyres?

I am considering a car that will need new tyres and the correct size will help when I am shopping.

Is there a common tyre that is widely liked to be used on these cars? Please believe me I am not trying to start an oil thread. I don't enjoy them one bit, but on an old dirt bike I bought recently the front tyre I was running was know by most people to be rubbish and once I changed it the bike handled much better. So I thought I would ask what tyres people like (not what is best) before I go to far into looking for tyres.

Cost isn't a huge deal as I think I will get years and years out of them.

You will get people saying that because profile is not stated in the tyre size then this means it is 80 but that is not necessarily the case. For example, for the 185HR14 tyre on the W114 280E the Mercedes manual states that it is a 75 profile. Ideally you will need to get hold of a manual that states this information for your car, or find out from someone who has one. If it turns out that the profile is 75 for that car, then a good alternative would be Michelin XM-2 in 195/70x14, as these are a very good tyre and about the only decent one in anywhere near the correct size. And the circumference of this size should be similar to a 185/75HR14. Tyres in that size are only basic cheapies.
