14" 5 stud factory wheel options ?

Hi all , I'm going to need 14" wheels for a 5 stud converted RX Turbo and I think the GX Liberty ones are going to be the lightest available . I'm trying to have the least gearing and speedo error dramas possible and with Michelin tyres the lowest profile its seems is 65 in a 175/185/195 . By my calculations the closest wheel circumference in a 14" wheel is going to be 195 60 14 if such a thing exists ie 23.212" vs 185 70 13 at 23.196" .

BTW what profile and width tyre did the early GX Liberty use .

Cheers Adrian .

Adrian - I had 195/60 R14 Yokohama Y352 tyres for a while on my L. They have an OD of 592mm (23.31in)

Sounds good , did you use them on the early Liberty alloy rim and if so did the tyre bag out much on their 5.5" width ?

I found that Michelin (love Michelin rubber) do a Pilot Exalto A/S tyre which they say is the Europenan all weather version of their Pilot Preceda 2 in
195/60/14 . Fingers crossed they are here in Australia and if they're in the same league as PP2's on the R33 the handling should be pretty good .

Any way the wheel issue for me is to keep the ratio of sprung to unsprung mass down because of the RX's low gross mass . Makes all the diference in the world to spring and damper rates .

Cheers A .

tyres and rims and speedo accuracy are a funny thing. My 15" superlites with 195/50 - 15' s are spot on dead accurate as far as GPS v speedo are concerned as was 175/70 - 14"s and to put the two different ones side by side you'd swear the 15's were smaller !!

No the tyres were on steel Speedy wheels (14x6). The Yokos were a good tyre - tended to wear a bit quick though. The figure sizes I quote are from the Yokohama site. I agree with Jono about double checking with a GPS.

My Commodore wagon was pretty close - speedo read 1kph (at 100) under actual speed with factory tyres. I recently got some 235/45 R17s (replacing 225/50/R17) - and these tyres make the speedo read 2kph less.

Before anyone asks how I know the 1kph difference - its because VZ Commodores have both a digital and an analogue speedo.

I am yet to scare myself and go drive my L Series with the GPS to see how "out" the speedo really is.
