Tire size

[Tekanawa]

Hi guys first time here, I've had a look through the forums, in hope of tire information. Now I have a 1992 irmscher, and currently have the standard 245/70/r16 (29inch I believe) so I am looking to put 265/70/r16 (31inch) and both times I've gone into tire places to get a price, they've both advised me not to get bigger tires.... To much strain apparently. I was wondering what you guys think because a lot of you guys have bigger tires and I haven't heard of too many extreme problems. So I'd like a general consensus on if it's okay to go bigger.
Cheers

9 out of 10 trucks of your model are running 265/70/16 tyres or bigger No issue
Life isnt always that simple though. First check your rims If they are 6 inch wide you need new rims You need at least 7 inch for that tyre and although some tyre shops will fit them you might get red flagged at wof time. Be careful with offset Space them out too wide and they will rub.
Is your suspension sagged at all. It does have to sag a fair bit before it causes issues
Speedo will read lower. On my Bighorn with the same tyre it was 98 at a gps 100 Ive just gone to a 265/75/16 tyre and speedo is spot on
I would be thinking that if a tyre shop doesnt want to sell you what you want the one round the corner most certainly will

Ive just noticed your age
Technically changing tyre size makes it a modified vehicle although Ive never heard of this tyre swap coming up as reason to force a low volume cert. In your case though because of your age insurance companies are already looking at you sideways and we all know they take any excuse they can to turn you down

Thanks greeves I'll take that into consideration and I'll check rim sizing, I'll found out about "modified" as the insurance is through my father. Cheers

Whos driving the vehicle? Insurance cos love to avoid paying out and they see the owner as primary driver. If they find the main driver isnt the name on the insurance they have in the past refused claims.
