TR6 Road Wheel Changes

Recommended Posts

Hi All

I have a March 1969 TR6 with 72 spoke wires, but am looking to replace with standard steel rims for the restoration.

I believe there was a change point for the road wheel but not sure of the chassis number involved. If there was a change how can the differences be identified visually, and are the earlier rims ( if my information is correct) a decent option? Did the early TR6 have rostyle trims, and are the centre embellishers the same throughout the range or did they change also?

Many thanks for any info..

Regards

Kevin

Be aware that you will need longer wheel studs for steel wheels.

Kevin,

As I understand it, very early TR6’s had quite a few carry over parts from the 5 including the dummy Rostyle hubcaps although I have to say that in 40 years of TR ownership I don’t ever recall seeing one. 

The steel wheels on the CP series car which yours is, had black wheel centres and would have been 15” x 5.5 J wide. On the later post 73 CR series cars, the wheel centres were silver to match the rim colour. I believe that a change to 6J (6”) wide rims was also incorporated but without going out to the workshop to check mine (1974) I couldn’t say for sure. The size is stamped on the wheel rim  

As the previous poster indicated,  you will need to change the shorter wire wheel spinner securing studs for the longer ones required to receive the appropriate wheel nuts. 

A very easy modification in either direction on TRs. Most other popular classics are far more involved. MGB for example has a different axle altogether.

Hi Mike 

Thanks for the info, I believe I have the correct centres ( as photo) and if the change point wasn’t until ‘73 I’ve got a good chance of picking up a set of 5 1/2 J wheels. I would assume the black centres will fit 6J rims also? Did they not update the font on the TR6 logo?

I wasn’t a great fan of the Rostyle trims on the TR’s even though I appreciate they are a rare item in good condition. They were better suited to the PI saloons I thought.

Regards 

Kevin

Hi Kevin,

This probably isn't what you want to read!:ph34r:

'The 1969 model can be readily identified by having rostyle wheel trim covers...

...the 1970 model year ...wheels with a black centre trim...

...In late 1972 the revised CR /CF series was introduced. ...chrome strips on the front grille, wheels with a grey centre trim' - from TR6 Register Buyer's guide

Thanks Pete

Time to put OCD purism to one side then in that case perhaps!

Funnily enough I'm not keen on wires on the TR6 even though I have and like them on my TR4a, and on all other TR's (except the 7), so I'll probably go for a compromise and settle on the 1970 spec.It's near enough!

Kevin,

Yes those would be the correct wheel centres for a CP series car. The font on my later wheel centres looks the same.  If you have to buy studs, wheel nuts etc you’ll need the plastic collars that clip over the wheel nuts. These apply gentle pressure on to the plastic centre springs preventing rattles. Many years ago now I bought a set of stainless steel wheelnuts from one of the regular suppliers. Once buffed up  on the bench polisher they were indistinguishable from chrome and no splitting off of the plating when you apply a socket. 

Very much personal  but tend to agree with you. The Michelotti bodied cars look absolutely right with wires. The 6’s less so as the design is so much sharper. Spend some of my retired time these days helping at a chums Classic car business. He has a customer with an immaculate Stag but it has wires. Somehow I’m not sure..........!

Hi.   For info ,  wires  were optional on the six up until may 73 .Early six steel wheels were not welded all the way round .From cp 50001 there were 15 cooling  holes instead of 12.               Chris

Hi Chris

Thanks for the info..looks like the later wheels will be a better option. As Mike has suggested I wonder if CP50001 was the change point from 5 1/2 to 6J also?

The TR6 had 5.5J wheels throughout production. No 6J wheels were fitted by the factory.

Cheers

Thanks for confirming that Derek.
