Looking to replace tyres on our 05 GLXR Triton. Its now fitted with 265x 70x 16 Bridgestone HT as fitted original done 82000km on these. Talking to the guy at a tyre shop. He said maybe go 265x75 x 16 AT Give it longer legs the Triton could do with that. Does anybody know how much it would put the speedo out or see any other problems

You should ask for the Light Truck (LT) construction in 265 75 R16. I got them about 6 weeks and are better on road than the H/Ts :)( only minimum use off road but so far so good). You can check your speedo against a GPS, which would not be more than 2 to 3%. My original tyres were 245 70 R16 and my speedo actually is nearly spot on (ML Triton speedo are all 5 % less than actually speed thats why you get good fuel economy :mad:)

You will most likely find it will make your speedo spot on the money! But never trust your speedo, unless you have checked it against a GPS or over a measured distance.

The speedo reads lower than the gps wasn't sure how much the tyres would change the speedo

If it is about 5k difference then going up one profile could fix that, I had the same thing (most people will) and went up a profile in tyre and now the speedo is spot on.

Have you tried looking at 275/70R16's? I think the legal limit of tyre size increase is 15mm change in diameter... changing to the 275/70R16 from 265/70R16 increases the diameter by 14mm, whereas a change to 265/75R16 will increase it by 26.5mm.

The difference in speed measurement will be 100km/h (265/70)= 101.77km/h (275/70) = 103.3km/h (265/75).

I just got new tires for the triton after squeezing out 100k km's on the set of bridgestones. (I think they were the same tyres when purchased - I bought the vehicle 2nd hand..)

I was told its 50mm for tyres, 50mm for suspension (from OEM specs), well in Qld anyway... Can anyone confirm/deny?

Yes and no, 50mm suspension, and (i think) 150mm longer rolling diam from the largest tyre on the tyre placard of your vehicle. You can also put in a 50mm body lift on top of all of this.

Yeah right! Awesome... then its just a case of finding an insurance company that will accept mods like that! I know RACQ will only accept 50mm on each (sus and tyre)... They told me no body lifts... or is that all just before you need to seek mod plates/certs?

"The rim diameter may be varied from the standard size
but the overall diameter of the tyre must not vary by
more than +15mm or -26mm." - QLD Transport

I dunno if raising the suspension affects this rule...

Yes it will come down to your insurance company, some let you do it and others don't.
Don't be afraid to change your insurance if your current one wont cover for the mods you want to do.
