MG Midget and Sprite Technical - tyre pressures
just wondering what others have thier tyre pressures for non standard tyres not sure what to put in my 165/70/13 tyres. |
mark heyworth |
start with 24 front, 26 rear and adjust to suit. |
David Smith |
I use 24/28 on the same sized tyres. |
GuyW |
24/26 on 155/80 |
C MADGE |
1.8 barg front and rear. Psi is so passe.... |
Oggers |
Presumably it handles like a barge as well then? |
GuyW |
1.8 bar = 26 psi. On 225/50r13 or 205/50r14 (?). |

Yeah I have trouble understanding why you would run more pressure in the back than the front when midgets are a bit nose heavy and fairly neutral with a crew on board Fith a full load of luggage i can understand but normally I'd think same all round or higher in the front compared to rear Just to confuse you I used to run 38F 32R (psi-sorry Oggers) in my Midget racer for best grip/temp results Anything under that was a disaster with tyres folding under load and that's with 48/52 weight dist. willy |

Tyre pressure recommendations always appear to be a bit of a minefield to me. It seems to be dependent on who you believe.
I was never able to find a credible answer for my Diahatsu camper for example. Our station LandRover has helpful stickers on the wheel arches specifying 30psi front and 45psi rear. But on Thursday I collected a second LandRover and drove it back from Perth; its stickers say 35psi and 60psi. They are identical trucks, both on identical tyres (BF Goodrich A/T). Both are set up nominally to tow a D class Lifeboat on a trailer, 720kg all up with nose weight around 20kg. I have queried the technical office, but no comment so far. My own last LR was also a Defender (although badged as a County) which wore the same BFGs (but on alloys not steelies like the Institution trucks) and I ran 32/40psi on LandRovers recommendation. And I've never heard a credible explanation for lower pressures at the front where the heavy ironmongery sits and where all the inertial transfer loads go under braking. |

I run the same size as Mark and use the same pressures as recommended for 145SR-13's in the Handbook: 22 psi front and 24 rear, and have done for years with good handling and no signs of uneven tyre wear. That said, I will increase them if I'm doing a long motorway drive, but that's very rare as I prefer to keep to the Wiltshire lanes. |
