    Default 10S Rims / Tyre Size?

    Hi All,

    Ive been given a set of near new Nankang 165/80/15 tyres off a VW Beetle apparently and was wondering if they'll fit on my 10S rims on an 8 or 10 or are they too big?

    Cheers

    Anthony

    According to this wheel-tyre calculator, the 165 x 80/15 tyre will fit on rims from 4.0" to 5.5"

    With the 10S rim being a 4.5", the tyre should fit easily.

    Wheel/Rim Size Calculator - Shows acceptable rim width range for the tyre size

    Of course check tyre clearances to steering arm etc

    and your speedo might be out a little (8% difference)

    I am less than enthused about Nankangs as wet tyres but they're free & you've got them . . .. I think that you'll have arch clearance problems at the front on full lock but you could always fit a judiciously sized spacer ring to compensate.

    On 4.5 rims my choice would be 155/60-13 (Smart tyres) as they're available in Continental's excellent EcoContact3. They have two merits for a rear-engined Renault: first, they are very good as wet braking tyres & second, they have very benign & talkative lateral limit behaviour in the wet.

    Compared to 135/80, gearing would be shorter by a bit under 4%. I have identical under-gearing with the rear tyres of my Djet, R8 & 4CVG & deem it not to be an issue.

    If anyone wishes to have "R10S" rims but has only 4" standard ones, my suggestion would be not to get 4.5" rims fitted to the R10 centres but to get 5.5" ones (with the same, or mildly increased, offset as the original) or 5" ones. Or, even better, 5" fronts & 5.5" rears. The motivation for this move from 4.5" is tyre related.

    Such rim widths suit the above-mentioned 155/60 EC3 & also suit an even better tyre, Continental's PremiumContact2, which is available in 175/55-15. The PC2 is better gripping than the EC3 in all disciplines & is more tautly structured & stabler on the outside tread edge (good features for the rear tyres to have relative to the fronts). The advantage of the 20 mm width difference is that one can achieve desired handling balance without having to lower front pressures to sub-optimal levels. So, 155/60 EC3 fronts & 175/55 PC2 rears.

    These two tyre sizes have almost identical circumferences & that is also true of 145/65-15. That last size will fit on a 4" rim & fit in the spare wheel well. There are no longer any good tyre types in the size but it's only a spare & Nankang's AS-1 would be the cheapest option.

    cheers! Peter

    From experience. Acceleration with the 165's will be noticeable slower.

    Yep it already has a Weber and Extractors Jaahn!!
    I do have a set of 13 and 14 inch wide wheels already aswell as the 10S rims. Might put the Nankangs on the 10S rims and see how it goes.

    I think you'll find they're way too tall Anthony, won't look right, and it'll kill your acceleration . It'll be quieter on the freeway though with the taller gearing equating to less revs cruising along at 80 mph
    cheers,

    John
