Can I put 205/65R15 tires on a TR3A?

I have a 1960 TR3 (TS61483L) that I’m redoing (again). I’m putting in the rack & pinion mod and have an unused original Judson S/C for it. The wheels are 15x5.5 mini lite mag knock offs. I’m leaning to 195/65R15, but I think the speedometer will be a hair closer if I can get 205/65R15s on. I know it’s not a big difference, but I think the wider tire would look a hair better too. Does anyone have experience with 205/65R15 tires? Specifically, can I get them on without rubbing anywhere? If they do rub, where is it, how bad, and when (all the time/just right turns/speed bumps??)? Is it just the rear fender and can that be fixed with a wider/longer support stay (601937)?

Any actual experiences would be greatly appreciated?

It depends on the offset of your wheels, but based on my experiences, I think you will have trouble getting those on without rubbing. I run 205/55-15 on TR6 wheels, and they still rub lightly in turns and bumps even after some light modification of the rear fenders. Not enough to damage the tires, but I can hear the rub and the sidewalls are polished from contacting the sheet metal. The rub is at the top of the arch, so extending the support makes little if any difference.

There is also significant variation from car to car, so you might get lucky. On my previous TR3A, I actually took the body loose and moved it sideway in the rear about 3/8" to get it better centered over the wheels (and still had rubbing as above).

Accurate speedometers are overrated anyway smiling smiley

FWIW, my long-term plan is to install 3.45 gears (from a PI TR6/sedan) to make up for the tire size. But running the shorter tires hasn't really been enough of a hassle to worry about (which is why I still haven't gotten the gears in after some 20 years running that tire size smiling smiley )

I’m quite happy with 195/65/15 on mine running 5.5 inch JBW minilites. I think 205’s would just be a little too wide.

I just bought a set of those (or similar) wheels from Rimmer Bros, in the UK and I've been wrestling between a 185 x 15 or a 165 x 15.tires. No problems with the 195s on the fenders or frame?

Based my experience, back in '68 when I first got the car and had to buy used tires at a local gas station, I assumed that anything much larger than a 185 would rub on hard cornering.

I have 185s on my 5.5 inch wide wires now, that have Moss sourced 1/4 inch spacers, so I still have my original lug bolts in place.

Knowing the problem that can come with wires over time and what a PITA to get them balanced correctly,I wanted a good alternative for road trips.

My father had mounted 205/15s on minotaur mini lite 5.5 x 15 repros. They fit and did not rub but were right on the edge of the wheel manufacturer specs. I thought they were too wide for the car and probably reduced handling. Went back with 165 Vredstein Sprint classics. Happy with them so far.

I’ve driven my car very hard with tight cornering and never had a tire rub issue with the 195’s.

I have 195 x 65 x 15 on 6” wide rims - see pic. You can put 205s on a TR3 but you will have to adapt the rear fenders for sure.

Thanks for the info everyone—looks like I’ll stick with the 195s.

BTW, Thanks for the great pix too. Mine will be similar to Tush. Planning Pearl White (w/a blueish pearl tint vs std Triumph) with blue interior and HT tho.

Cheers,

BG

Very cool indeed. What are you using for seat belts? 3 point retractable? Also how about some pics of those seats? Finally, are those aero screen mounts the ones that Peter Wigglesworth in the UK makes?

Four-point harnesses and pic of the seats attached. Seats and racing sidescreens sourced from Racetorations in the UK.The aeroscreen mounts are from Peter Wigglesworth in the UK (nice catch !): much nicer than the ones available in the US and do not require drilling new holes in the scuttle.
