Tyre

Tube

Tubeless – The chrome wheel has been tubeless since December 2018; and the silver-painted wheel has been tubeless since June 2018. If you have the older, tubed wheels or are fitting tube-type tyres you will need 135/145 x 13 tubes and we recommend 13″/14″ rim bands.

Notes

The Sprite Mk I was originally fitted with 3½” x 13″ steel disc wheels using brake drums at both front and rear. The conversion to Girling disc brakes at the front entailed the conversion to wire wheels. Early 1961, new Lockheed disc brakes, the so called “thin discs”, were introduced, which did not require the conversion to wire wheels any more. However, silver-painted wire wheels were offered as an option.

A small number (around 20 cars) were manufactured in 1962 with wider rear axles.

Slight modifications may be required for “Square Wheel Arches” axle may sit further to right/left.

Notes

As far as we are aware this wheel should fit with no modifications but, as with all non-standard options, a fitment check is recommended.

Warranty

Stainless Steel and Chrome: two year structural and cosmetic
Painted: two year structural and one year cosmetic

The warranty period commences from the date of invoice and is subject to the wheels being maintained as per our Wheel Care advice and in conjunction with our Terms and Conditions. Please retain the warranty tag supplied with each wheel as it contains the information required to identify the wheel in the event of a claim.

Please note: ACWW warranty automatically becomes void if the wheels have been: subject to re-work or change; fitted with tyres other than the manufacturer’s recommended fitment; or used for track events.

Splined Hubs

Option 1

When converting from steel wheels to wire wheels we would recommend the bolt-on splined hubs are used as the integral splined hub conversion requires extensive modification – half shafts to be replaced at the rear and the steel wheel brake discs replaced by wire wheel discs.

If converting using the bolt-on hubs you will need to check the clearance on the front brake pipes.

Option 2

Bolt-on splined hubs (Drum Brakes) (please contact us):
RSK193 – Left
RSK192 – Right

Four RN38NYLOCK per hub

The first time you fit bolt-on hubs it is recommended that customers purchase an additional spare nylock nut to use as a cutting guide.

When fitting: place the bolt-on hub onto the studs and screw on the spare nut; cut the stud down; remove the spare nut; apply the spare nut to the next stud and repeat. When all the studs have been cut down to the right size fit the hubs using all new nuts and dispose of the spare nut.

This advice applies to the nylock nuts but not the standard nuts because of the safety implications of any damage to the nylon inner.

If you have to remove the nuts for any reason in the future then as long as the nylon inner is undamaged they can theoretically be refitted but for safety’s sake we would recommend they are replaced.

Early vehicles (Mk I) are fitted with Drum Brakes all round and may require 8mm spacers to offset the hub.

Front disc brakes became standard with the Mk II in 1962 for vehicles with the 1098cc engine. Mk II with the smaller 948cc engine still had drum brakes.

If converting from steel wheels check the clearance on the front brake pipes

Bolt-on splines will increase the track by up to 1¼” per wheel

Studs will require shortening

Option 3

Integral fitting splined hubs (Disc Brakes) (please contact us):
RSK111 – Front Left
RSK110 – Front Right
RSK109 – Rear Left
RSK108 – Rear Right

These integral splines are 8 TPI, however, Mk I & Mk II (1958 – early 1964) may have 12 TPI splines – please check before ordering

12 TPI splined hubs are available to special order

Integral fitting hubs so no nuts necessary

Notes

We recommend using our 42mm wooden spinner saver to protect the knock-on caps (spinners) when using a copper and hide hammer.

XW5797: Due to the positioning of the centre in relation to the rim you will require an extra-deep wooden spinner saver
