It's not the size of the wheel that matters,it's the overall diameter of the wheel/tyre combo.
13" wheels with 185/70 tyres have same as 16" wheels with 205/45.

Does this apply to 1.4 Supersport and early 1.6 Supersports which were the only K engines to be specified for 98 octane fuel in Caterham brochures,etc.?
Keith, Demon Tweeks, although I imagine any decent car place could order from Millers.
DT price:£2.97+VAT+postage for 250ml which treats 50 litres to give a 1.9 octane boost so you might be OK at 'half-dosage' although I'm not sure if the dosage requirement is 'linear'. Jerry Parker.
For Keith: Yes,you're not the only one to notice the drop in SUL octane, the answer for me is Millers Octane-Plus C, which is safe for cats and gives a 1.9 octane boost.

Miller's VSP Plus (available from Demon Tweeks).Endorsed by FBHVC (only four products passed their tests) and gives a 2 octane boost so ideal to add to 95 octane unleaded to give protection and correct octane. Jerry Parker
