My original tires were 185/65-14 and the 195/60-14 were only a slight change in circumference and revs/mile. 
Not sure about the fit on your car. 

 

	tire dia. (in)	tire circum. (ft)	tire revs/mile
195/60-14	23.21	6.08	869
185/70-13	23.20	6.07	869
185/65-14	23.47	6.14	859
185/60-14	22.74	5.95	887

 

Thanks, appreciate the info. Mine is a 1990 Super Seven. I’ll get to measuring tomorrow. I think they’ll fit.

The reason for 13's is not for weight saving.  The taller walls you will have with a 165-185 absorb a lot of road and are better in cornering.  

The rubber selection for 13  or 14  is scant regardless.  

I think your 14s are about perfect and I would trade my 3.75 13 minis for 14s any day.

I did the math on the tire sizes - 185/60 in both 13 and 14”, and both have the same sidewall height, the only difference is the circumference is an inch smaller. 
 

I’m going to look into the 195/60r14 for fit.

I expect you will hear a lot of folks tell you to go with 13" rims for weight savings, if not tire choice. I have 13" wheels on my Lotus twincam powered Caterham. 

Yeah, I was thinking 13" as well for the same reason. What size rims should I look for in 13"?

My car has 14” wheels and I’m running Falken Azenis RT660 tires (195/60R 14]. They are reasonably sticky and I find them to be good for road use.

Ah, thanks! I currently have 185/60r14, and meant to ask whether 195/60r14 would fit on the car. So, thank you for your help! I wasn't finding much in 185/60.

My 1990 Super Seven has 14" Panasports, and given the few 14" tire choices, wondering if I should switch to smaller 13" wheels, or go up to 15's. The car is fairly new to me, and came with a set of fairly old Bridgestones. I feel that 15" wheels and tires might add more weight, given I have a Lotus TwinCam and not a more modern engine, I'd rather not give up HP pushing extra weight (I'm already too much weight! )

 

Thanks for any advice/opinions. 

Sorry, should have added that I just drive the car on the street, and while a track day isn't out of the question in the future, for now, decent handling street tires are my priority.
