33" Tyres ....Too Big ???

[Rover110]

Hi all,

Went to Bob Jane T-Mart today for a wheel allignments and a balance. While i was there i asked about wether 33" tyres (Cooper ST's) were practical for my 200tdi defender 110. I was told that they would we too big and i would lose a lot of power. I have been told this by several people now.

Has anyone got 33's and what have you found with them performance wise?

Thanks
Jordan

well considering a standard tyre for a fender is 750x16 which measures about 32.2" think safe to tell them they better actually go read the manual :D

thats exactly what i thought.

i have run 33's on a 300tdi defender and i found them to be a better overall package on a std defender than the 7.50x16's it hasd on it as std.

speedo suddenly becomes accurate, smoother ride, and more height under the salisbury anchor...

i run 33's on my current county as well.

Actually 7.50R16's are 31.6" ;)

We're running 255/85R16 M/T's (33") on our 300Tdi Deefer. We're getting a much smoother ride, better grip, speedo closer to actual speed, no discernible difference in power, and most importantly 3/4" extra clearance under that salisbury :D

As above.I would put 33's with the traxide headlight kit,a worthwhile improvement on a defender. Pat

And just for the record they don't sell traxide kits at Bob Janes :D

My disco 300tdi auto, tuned up (61kw at wheels hehe :)), had no probs going from standard 29" tyres to 33" muddies. I thought it would die in the arse, but it handles it fine, even on standard diff gearing. Cruises well at normal speeds etc.

Don't go to Bob Jane even here in Newcastle they dont know what they are on a bout i was over charged $300 for mine i was lucky i checked the papers other wise i wouldnt of noticed. Also they like to add suprise costs.

We have just put 33's on our non turbo isuzu county, couldn't be happier didn't even noice any difference in gearing;)

TIM.

i have a 200Tdi defender 110 and i'm running 285/75/R16 (33") on 16x8 rims. originally noticed minimal surge in fuel usage and loss of rolling acceleration. replaced standard exhaust system with a 2.5" system from the turbo back. everything back to better than normal.

Cowboycammo.... is that 2.5 straight thru ?
