Tire Size Options? 1980 300SD
« on: 09 October 2019, 07:50 AM »
What tire size(s) are correct for a 1980 300SD.  The car currently has 215/70x14 tires that are worn and needs to be replaced.  The specs seem to show 185/70x14 as correct. A mechanic friend who is a mercedes specialist tells me 205/70x14s.

Thoughts?

Whatever the specs may show, you're going to be happier driving on the 205's.  Unless you're into a purist, all-original thing, I'd go to 15" wheels and go even bigger.  I'm running 235/60-15's.  The difference in comfort and handling is profound.  And you'll have a lot more tires to choose from.

205/70 is optimal for the suspension setup. Some go 215 or 195 depending on budget.

I run these. Good quality and inexpensive. https://www.ebay.com/p/740187110

185/80R14 is the stock size. 195/75R14 is usually easier to find, and am what I am currently using. 185/70R14 would be too low in profile and would cause speedometer error.

I think I can use a tire "primer" on tire performance.  Let's assume that the rims can handle tires measured at 215/70/r14 or 205/70/r14 or 195/75/r14 or 185/70/r14.

Why would one be better than the other?  What is the upside of going with a larger tire?  What is the downside with going with a larger tire?

I personally like skinny tires because they help with fuel economy, get better traction in wet and snowy weather, make steering easier, and give the car a nimble feel. Wider tires make the car not lean as much around corners or something. They also get better traction in dry weather on a clean road.

Based on all the input, I think I am going to order a set of all weather 205/70/14s.

All weather tires aren't good in any weather... go for either summer tires och winter tires.

Outside of the extremely pricey Michelin XWX and Pirelli Cinturato CN36, summer tires for a W116 are non-existent.

Unless you go 15" that is.
The 14" world is a sad, expensive place.

Depends on the tire and climate. They're great in moderate climates, like the Irish.

you can get falken ziex ze914  205 70 14 summer tyre, i have them on mine,  and i remember that maxxis did a good well priced tyre in that size

options are few and probably getting more expensive.

I run Falken Sincera on the 6.9. Not great but not bad for occasional use. 15 inch is the logical upgrade as the choices open up dramatically.
