Hello,

I just bought a great X300 from 1994. 4,0 Sovereign. However, the tyres need replacement.

Currently, it has 225/60-16s. But I was wondering, if 215/65-16 could do instead? Or 215/60-16..? They are substantially cheaper..

Thansk in advance.

Best regards

CJ

 

A few things to consider in your decision (but things you might already know):

The original size is 225/60-16. A variation in width or aspect changes the sidewall height. In this case, a 215/65 will be slightly taller, while a 215/60 will be slightly shorter than the 225/60. A change will slightly affect the speedometer and odometer accuracy. Also, the final drive ratio will be a little different.

More importantly, the original spec for load rating is 97. The 215/60 is usually carries a 94 or 95 load rating. If you look around you can probably find a few in this size with the XL rating which is usually 99. Falken Ziex is one example. Choices are limited. I see that most 215/65 tires are load rated at 98 or above, so no worries there, and many choices.

The original Z speed rating is equivalent to a V rating I believe (V+?). I think it is a good idea to keep to at least an H rating, if not V. But don't take H rated tires out on the Autobahn!

A tire shop might refuse to sell you tires that have a lower load rating (or too low a speed rating) than the originals.

Some non-USA cars have sport suspension which would include wider 8" sport rims. I don't think the narrow 215s would fit or look right on the sport rims.

 

Thank you for the good answer. I know about the pro's and con's in terms of speedometer readings etc. But was also curious if any of you had tried other sizes?

Cheers

Be Careful! My insurance company gave me permission to use lower speed rated tyres than originally specified - and warned that without this authorisation, my insurance cover COULD have been made void!

 

Carl , for what it is worth, my Daimler 6 (1995 3.2) wafts along beautifully on Michelin Primacy 3ST 225/60 R16s . quiet, good handling, good wear. 120km/h feels like 90.
