Tyre Size

[Monaro Pete]

Hey guys.
This has probably been asked before... I've had a look around the forum, but it's a needle in a hay stack scenario.
What size tyre (in circumference) can I go up to without any problems?
I'd like to leave the mud flaps in place, though I have no objection to trimming them if I have to.
I see Elty has had 265/75 15s fitted in the past on his project thread, but he did a 2" spring lift too.
Are 265/75s an option at standard height?

The new truck is nearly ready for some new boots & I'd like to bring the speedo into line with the correct speed & lower the revs slightly at speed.

You defo running 15" rims? 265 75 15's are 30.6 inches, I have 245 75 16's which are 30.5 inches, I ran them with the standard/old/worn and sagging suspension with no problems at all, I have a lift now but had no probs before the lift :thumb2 I'm going an inch bigger next time with 265 75 16's which will be approx 31.6 inches. The actual size of the tyre varies a little with manufacturer too!

Doh :doh

Silly me, I don't know why I put 15". They're 16" rims :lol

Also the manufacturer and tread pattern can make a big difference to the overall size.
The only problem i had running tyres that wide was them rubbing on the power steering box on full lock.

Thank you both for your replies.
Looks like I'll be needing some spacers :lol

I've been running 265/70R16's now for a little over a week & all I had to do was trim the front mud flaps a little, because of the extra profile. No rubbing anywhere else.
No spacers where needed. My speedo is now 1mph over than true, which I can live with

Thank you for your advice :thumbs :thumbs

Having read, re-read, and then read again, I take it you mean 265's? I run 235/70 16's which are not even close to touching anything.
