Odd rumbling noise when driving

[justinstandring]

There is an odd rumbling noise when driving. Seems to be related to wheels, probably front. Seems to be worse when warmed up. All tyres are new & wheels balanced, although still a mild shudder when over 50mph. But it is the rumbling which is a new sound I am worried about. Any ideas??

My Tires were very, rumbly/noisy until I got used to the fact that these Hi load tires actually need 41 psi up front and for me 46 psi out back.

Running the Conti's and they are smooth and quiet now. No shudder,, smooth as a Cadillac and handles like a sports car :P

I got mine used with 20k miles on the clock. When I buy used I always Dismount tires and have a look Inside,,ALWAYS !

Rear tires looked like new, (Tread was slightly deeper mid tire) due most likely to only 38 psi.. still on at 55k and still ""look"" new~

Rear ones make a little noise now, At 55k tread depth is at 7/32"s I may replace at 70k miles.

Found about 2 cups of tire rubber inside a front one,,this means some fool ran flat for a few miles or at least ran low psi..

Off comes the front tires,,one to keep as a backup spare, the powder tire to the dump.

Two New Conti's (With a very different tread pattern) went on at 20k,,

Note: I am not rotating so now at 55k the rear tires are even at 6/32" and the fronts are at 6/32" with 35k BUT

They like many tires wore down from 10/32"s to about 7/32"s real fast and seemed to stop.

I do not rotate because I am timing tire wear out so I can replace all four at about 70K then I will rotate every 20k

With this set I have been brutal,

I take off ramps fast and enjoy the flat and level sports car handling ~~~~

I always remove tires at 4/32" because some time before the wear bars contact the ground I hydroplane at super slab speeds..
