    Default floride tyre sizes

    Trying to sort out which tyres to buy for a 1960 floride, the recommended size is 135x15, i have found a dealer who has Toyo 310 135x15 tyres in stock, would i be better fitting them or go to the easier to find 145x15, what do you have on your floride?

    The last tyres I bought were Nangkang, but I didn't like them at all and wouldn't recommend.
    Otherwise, you seem to be a new Floride owner, photos please, what have you got?

    You'll get a good range of comments/responses to that question!

    Standards are indeed 135-15, and Michelin XZX are available in that size, $200-250 each. They are a Michelin classic size, made in batches with modern structure and compounds and, personally I use them on my R8 and 4CV. They are much better than the original XZX tyres but of course a dated tread design. You can get them in 145-15 too. They are available locally in Oz or direct from Longstone UK.

    Firestone makes/made a 135-15 tyre too although I've no idea whether we can get them in Oz. They seem OK.

    Moving on, and others will, if you change wheel size a bit, the world opens up with 14" rims, but then it is what floats your boat and what you do with the car really.

    Have you considered joining our Renault 4CV Register of Australia? We cater for all the rear-engined models. Google will take you to the website.

    135/80

    The original tyre size was 135/80-15. This is now available from places like Longstone tyres in England in Michelin's "Classic" range ZX. This is the closest you'll get to a tribally & period correct fitment. It needs a tube & (V.A.T.-free) price is around £90 (plus freight). So: it's dear & buying locally from specialists like Antique Tyres isn't really cheaper & I'd have worries about local stock age (tyre compounds suffer even when unused on a shelf in the dark). Longstone do do discounts for 4 & might deliver free (it's not clear but you could email & ask them).
    But importantly, even though upgraded in structure & compound it's still a poor tyre in the wet & that gets relatively worse when the water is deeper.

    Much cheaper (around $80-90 as I recall) & available locally is Nankang's CX 668. Another merit is that it's tubeless (always favour tubeless tyres if you have a choice even if your rims originally had tube-type tyres). Again, a concern is stock age in a rare local size but you can always make it an explicit "in print" condition of sale & payment that the manufacturing 4 digit date stamp on the sidewall will be no more than 18 months ago.
    But again: it's a poor wet tyre.

    145/80

    One size up (& widely used on rear-engined Renaults) is 145/80. Very mild over-gearing is a trifling objection to moving to this size & it fits the rims (as do all of the stated options).

    The Michelin "Classic" option is the (updated) version of the tyre which replaced the ZX (which itself replaced the original X). This is the XZX. It's a better tyre than the ZX as the more rigidly stable shoulder area aids cornering response.
    But despite more modern compounding, it's still a poor wet tyre (modern low-end Michelin compounding is not wet-grip biased). It's a bit more expensive than the ZX &, like that tyre, regrettably demands a tube.

    Longstone also sell the Firestone F 560 in 145/80 at about the same price as the smaller ZX (but it might be that a slightly cheaper price is negated by the non-availability of a possible special freight deal on the Michelins).
    Anyway, like the ZX & XZX, it's a poor wet tyre.

    155/80

    Still possible on a 4" rim is 155/80. Obviously a bit more over-gearing compared to the original 135/80 (about 5.5% taller) but I wouldn't deem that to be forbidding. I mention it because one interesting tyre is available in that size: Michelin's "Classic" Xas FF. The 'FF' (for: 'Formula France') was a version of the Xas with a softer compound for racing. It wears out faster than a ZX or XZX (or regular Xas) but grips better in the wet (& is not as "snappy" on the limit). However it costs twice as much as the other Michelins.

    145/65

    At this point in past similar missives, my comment has been that all of the above options are poor in the wet. This is important on a rear-engined Renault under both braking (front locking) & cornering (front or rear slides & too slow a steering ratio for easy, tidy recovery). You don't have to drive like a hoon for this to be salient - just have a "moment". The Michelins are also expensive & the Xas FF, although the best "wet" option, is very expensive. So far, so gloomy.

    Then, in the past, I'd say that salvation is at hand, for a very good wet tyre is available locally at no great cost & in a size (145/65) which involves but trifling undergearing of a bit under 5% compared to a 135/80. This was Continental's EcoContact3. It was by far the best option for standard rims unless one was tribally committed to Michelin on originality grounds. But it's no longer available in Australia :-((

    What is available in Australia in 145/65 is another Nankang: the AS-1. This is a much crisper responding tyre than the CX 668 (or any of the other above options, partly because of its lower profile). It's not as good in the wet as the EC3 but better than any of the other options except possibly the FF if the water depth were not to be threatening aquaplaning. I use 145/65-15 as a "spare" size for three of my toys. Two of those spares are EC3 & one AS-1. After a flat on one toy, my Djet, I had the AS-1 as one front tyre (the other a 165/65-14 Conti PremiumContact2) with about 10psi more pressure than the other front. The road was wet & I had a play in the cause of advancing human knowledge. My judgement was that the AS-1 (although no PC2) was not bad at all. Certainly better than I predicted.


    So, if I had a Floride on 4" rims & wanted 4 new tyres, I would buy the 145/65-15 Nankang AS-1. It's cheaper than any other option save its very inferior CX 668 sibling, is crisper handling & better in the wet. It is also tubeless. (Do not let an ignorant tyre tech try to fit tubes. Two reasons: first, 65 is too low a profile; second, tubes chafe on the ribbed inner lining of tubeless tyres. Tubeless is technically fine on your rims - a long story which I'll only tell again on request.)

    cheers! Peter

    Tubeless is not always the go as the rims are rivetted and these often leak. If you need tubes and cannot get the right size for the tyre choice then fit 13 inch not 15 inch as larger size 15 inch tubes will crease and go flat at the worst possible time.

    I'm assuming that standard 15" is the governing choice. Rivets are not a problem & as any manifesting potential slow leak is easily remedied by sealing. I haven't had to do this but yes, it is a possibility.

    Were I to be wishng to retain something like the original wheels then I'd mildly upgrade to 4.5" rims via a wheelwright. I understand (from Colin's Kermit) that Citroen GS rims have a wheelwell depth which will mate with the Renault centres &, given the paucity of R10S wheels, that's what I'd choose. The merit of 4.5" rims is access to a better tyre type than any of those available for 4". This is the estimable Conti EC3 (mentioned earlier) in 155/60 (same circumference & sidewall height as 145/65). A very nice semi-stealth upgrade.

    cheers! Peter

    I forgot to comment on the 310. This is an old type & poorly compounded for wet grip. It is no longer a Toyo Australia standard line although people like Tempe Tyres & Australia'sBestTyres list it. Grey imports perhaps? Anyway, I would again worry about stock age.

    Generally speaking, if there's a choice of 145 or 135 within the same tyre type, then I'd choose 145 for dry grip. (The CX 668 Nankang is available in both too.)

    I'd still choose the AS-1 as the pick of a bad bunch.

    cheers! Peter
