Unless the missing aspect ratio is something bizarre, it certainly does exist. I have a set of four on my ride that match the original spare in the trunk (175/70/r14)

Shaves a few miles off meaning decreases? And are we talking wagon wheels or the wider tires?

The non aspect ratio tires actually exist. They are the more or less equivalent to a " 83 " ish series. This non aspect ratio listed tire was also found in 15 ( Like air cooled VW / pre 81 SAAB 900 and others ) and probably other sizes. |

Yes, the middle # used to be R or SR, it's equivalent of now 70 .
I measure the defenders and they were the same diameter, for me this is important ans I like to drive long distances across the Desert and don't want to buzz my little 240D's engine to death . 'unpsrung weight' means the weight of the axle as well as the wheels and tires . Reducing it anyway you can, improves handling and traction through corners and bumps at speed . The light alloy wheels (disc typ on my 240D, Bundt typ on my coupe,) reduce the amount of power necessary tp get things rolling, meaning ,ore power available to get up to and maintain speed . When folks talk about "German Engineering" mostly they have NO IDEA about the importance of the small details, Mercedes does, why our 40 year old W123's are still going strong and are a joy to drive . Fat tires reduced driving enjoyment sharply, this is why Hot Rods aren't driven much after they slap on those HUGE wide tire$ . Power steering helps a lot but the -feel- of the road, is lost .

Here's another question... say I decide to replace the two front tires which are more worn than the rear, would it be a bad idea to replace those with 185/195 and make sure they were always a pair when rotating front and rear? Or is this unadvisable?

A set of four of these tires is very inexpensive. Go pick out a brand name (not Chinese) and you will be happy. Michelin, General, Bfgoodrich, Goodyear, etc... will all work. A set of four should be under $400. Enjoy worry free driving for the next 50,000 miles.

Why not buy 195s and put the fresh rubber on the rear?

Some folks don't use these cars every day, or drive a lot of miles, so the tires will rot out before they wear out. I see no problem with running a pair of 185 0r 195's on the front, and run them till the rears wear out. However, you could buy four new tires, and save one of the best tires for your spare. I have also had experience with ruining a good tire (road hazard), and needing an extra matching spare. In this case, it wouldn't hurt to save the extra good tire just in case. I personally have several 123's around at all times (five on my insurance at the present time) , so having good extra tires around is never a bad thing......Rich

The best thing to do when selecting an alternate tire is to use the manufacturers web site ( or Tire Rack ) and look at actual tire specs. They will show actual unloaded diameter, revs per mile , tread width , overall width. For the most part, a specific size of tire will be within a small margin across all brands. |

That’s a great call. I mean the lack of consensus here is astonishing: 175 Sr 14????? 220/8 (1971)
After a peep on tire rack, I’ve learned the aspect free original tires had a diameter of 25”. 175/70 are around 23.8, 195/70 are 24.8 which is about as close as I could get to the original.
