    Yet another Tire Question....

    I was checking my tires this morning because we am considering participating in a local event next month that will be more spirited than we've been driving the Fulvia thus far (called Cento Miglia, 100 mile rally/scavenger hunt in the North Georgia mountains). I noticed the date code was 2001 so I've decided to replace them even though there is plenty of tread.

    I'm also going to take this opportunity to put the correct size tires on the car (1968 Fulvia Coupe Rallye 1.3) and am surprised to see I actually have a choice of 145R14's here in the USA. Unfortunately, my favorite tire for this application (Vredestein Sprint Classic - use them on our Lotus Elan and love them) is not available in the right size.

    So, looking at the two choices - Pirelli Cinturato C67 (https://www.lucasclassictires.com/14...-145R14PIR.htm) or Firestone F560 (https://www.cokertire.com/firestone-f560-145r14.html), which one will be the better choice and why? Please do not use Price, Gas Mileage, or Mileage life be part of the consideration. We will only drive the car about 1000 to 2000 miles a year and both are well within tire budget for this car.

    Thoughts? And also, wouldn't mind hearing opinions about going from the existing 165 size to 145. I think it will be more appropriate and give a lighter steering feel.

    In terms of performance, I doubt there's a lot of difference between the Pirelli and the Firestone; with advances in construction and compounds, they're both likely to be far better than original.

    As far as going from 165 to 145, I suspect you'll gain more handling in lowering the ride height by 3/4 inch than you'll lose in lateral grip. You'll gain some steering response, too, but probably not enough to notice.

    Re: Yet another Tire Question....

    Thanks, Ed.

    I think it will be better to drive with tires that are not 17 years old regardless of size!

    Follow up questions (I know, never ending):


    • Tube or Tubeless? I pulled out the spare & it was an old 145R14 Michelin ZX, date code 1975 with Tube. I don't think the current ones are mounted with tubes but can't tell. I can easily get tubes and if they are not needed, display them as souvenirs of a bygone era.
    • What is the recommended method of lowering the car 3/4"? I may put that on my future to do list when I'm working other projects.
    • I've read all the threads on air pressure. Is their a consensus on best for mounting modern tires with or without tubes? I'll go back and read some more and also compare to my notes on what I'm using with the Firestone 165's that are currently mounted.


    My local independent tire specialist has a relationship with Coker so they can get the Firestones from them and they also happen to be a Pirrelli dealer so they can those as well. I'll discuss with them their preferences since they will be mounting and balancing.

    The 3/4" drop was going from 165 to 145 -- unless by "165" you mean 165/70.

    I've only dealt with alloys. The original tires would have run tubes, but that doesn't necessarily mean you need to now. I'd talk to your tire fitter, and see what they're comfortable with.

    Re: Yet another Tire Question....

    Given a choice I would between Firestone and Pirelli I would go for the Pirelli all day long. I had the Firestones on a Flavia and felt they were horrible even though a few years old. Out of preference I would mount Michelins on Lancia and preferably tubeless. I have to run tubes in one set on Michelins on alloy not because of the wheel design but because the tyre was made without the inner tubeless sealant on its inside on purpose by Michelin. I run Michelins tubeless on steel wheels on my Flavia. Beauty of running tubless is water cannot get into the steel rim via the valve hole and start rotting the wheel from the inside.

    Re: Yet another Tire Question....

    I went with the Camac's in 145/14 and run Michelin tubes. When I got mine last year the Pirelli's were not out otherwise I would have gone with them. On my steelies I am running tubes and on my Stilauto alloys I run tubeless. It seems you can go either way so I just picked one.

    I see a big difference in slow speed handling between 145/Steelies and the 175/alloys.

    Re: Yet another Tire Question....

    Thanks to all the feedback. I'll call my tire shop and ask them to order the Pirelli's (or if they prefer, I'll get them). I'll also listen to their advice about tube/tubeless.

    Next steps - do it. (and get out my books and research the proper torque for the lug nuts....)

    Re: Yet another Tire Question....

    I’m not sure what the torque specs are on the lug nuts. I ordered these when I got my steelies as I read somewhere that the originals were brass. Is that what you have?

    Not sure. It has the hub caps on and I haven't taken those off yet. The original nuts are most likely still on. Not much of the car is not original (except what we did). I'll check later this week after I get the tires ordered, appointment made, etc.... I'm not trying to see if I can get this project done by this weekend for a mountain drive that I originally planned to drive the Alfa on because I know the other participants would go crazy over the Lancia.

    The original wheel nuts are open bronze nuts (with a shoulder and tapered seat).
