| Tube | The chrome wheel has always been tubeless. The silver-painted wheel has been tubeless since February 2019. Tubes are only required if fitting tube-type tyres. If you have the older, tubed wheels or are fitting tube-type tyres you will need 550 x 16 tubes - available with a metal (race) valve or rubber (road) valve - or 165 x 16 tubes - contact us for price and availability - and we recommend 15"/16" rim bands |
|
| Notes | Ace and Aceca were originally fitted with 4" x 16", centre laced, 48 spoke wire wheels, which have never been offered by MWS. A fitment check is recommended when fitting the XW5786 or XW5787 on AC Ace, which had originally been fitted with these 4" x 16" wire wheels. By 1957 this wheel was replaced by inner & outer laced, 56 spoke wire wheels. From 1959, 15" wire wheels were offered as an option. The majority of vehicles were factory fitted with painted (silver, cream or red) wire wheels, however, a few were originally fitted with chrome wire wheels. |
