tyre drag
« on: January 22, 2008, 20:41:52 »
been running wider all terain tyres but standard size on the disco for the last six months and swapped them back onto the wife rangie yesterday ready to put it on the road ie mot tomorrow
drove the disco up the bypass up a hill and have only been able to do 60mph top speed
drove the same road today with the normal road tread tyres and managed to do 70mph top speed
question is do i keep the normal tyres and save fuel or keep the chunky tyers for looks
won't be going off road in the rangie as it's not got any dents or scratches on it and i got the other rangie for that


love's mud and lpg and the wife

narrow tyres and get better mpg and money in your pocket.

Good question,

i must be weird  :lol:

when i swapped to 31 inch tall tyres in my 90 i could get 80mph ( really didnt feel safe ), then they died so i swapped to some 32inch tyres but half an inch thinner ( so only 10 inch ) and no i can average at abou 65mph, but they work good off-road so might aswell keep em

What i'm having difficulty with is why would you want an off road car to go fast, is not tho point to amble about slowly? After all you may break something if you go fast.

Because it's an indication of how much rolling resistance he is experiencing, though I suspect that the subtle change in gearing from new, bigger tyres also plays a part.

My disco is an off road one. Ok not a serious off roader with trimmed wheel arches and lifts etc, but I do take it to pay and play days etc. For those days I put on my set grizzly claw tyres.

However, most ofthe off roading I do is down tow paths, muddy festival field, on and off campsites with a caravan. So most of my driving is up and down motorways and hi speed obviously. Although the grizzlies would be fab once I get to adestination they are a real hindress gettingto places as the max speed I dare do on them is 60mph. they melt whilst towing long distance or higher speeds, mpg is reduced, road noise is like a jet engine following me! So for the long distance stuff I have bfg at's. Same size as the grizzlies 235, 75 r16. Standard disco size.

So anyone with an off roader who travels alot on motorways wil want high speed tyres. If it is on theback of a trailer and taken to sites then, I can see your point, why would you want high speed tyres.

Al comes down to the distance you need to travel in the end I think.
