Hi I am looking for new inner tubes for my Gravely L8 size 4.00x8 . The problem is all the ones I have seen have the valve stem in the middle instead of offset to the side. Any one know where I can get inner tubes with the correct valve stem and are decent quality???
I have already checked the local tsc and rural king. All they have is the wheelbarrow style tube that has the valve stem in the middle. I am looking for a tube with the stem offset to one side so it will fit the gravely rim better.
You should compare the cost of new tires to the inner tubes. I recently paid $17.50 ea for 15x6-6 Kenda's for my lawn trailer. Tubes would have been $10 to $12 each. Tires had a lot of cracking .
I second that. Just put a pair of 16x6.50-8 Carlisle Turf Saver tires on my Bunton for $55. New shorty valve stems are cheap too. One of the wheels had some rust inside the valve stem area because the PO used a tube. Tubes don't seal the inside of the wheel from the outside at the valve like real valve stems so water gets inside and corrodes the heck out of the wheels. I cleaned off the rust, welded the old hole closed, and drilled a new one 180° around the wheel for the new shorty valve stem. Spray on some paint and 24 hours later I had a pair of tubeless tires mounted and on the back of the mower.
My Horse I & Horse IV tillers run 4.80/4.00-8 tires. You can get that size Carlisle Power Trac AG/Bar treads for $38 each and the Carlisle Stud tread for $32 on Amazon with Prime shipping. They'll probably outlast you. My Horse I tillers first set of tires lasted from the 70's till a few weeks ago.
Miller Tire sells 4.00-8 tubes. The web site doesn't say whether they have offset stems, but the last batch of tubes I bought from them did.
