    Hello Folks, I am needing to purchase a 48 x 102 because my 2005 MAC needs extensive welding repair.

    Looking at a Reitnouer that has 3 axles having super singles. Wonder if I could remove the center axle and run as a spread. Dealer measured the spread between front and rear axle at 103" (8'7"). Is that kosher for weight hauling legal limits?

    Thanks

    You could go 38k on the trailer axles with the 8’7” spread.

    Is it legal in all states at that distance?

    I know my 53’ with a 10’2” was referred to as a California legal spread.

    Federal bridge chart says greater than 8 but less than 9 is 38k for a 2 axle group.

    Your trailer is probably legal for CA’s king pin rule.

    I think the 40' bridge in Commiefornia is for trailers longer than 48'. I pulled glass in and out of CA on 48's. Some were 10' spread step & flat, others were 48' double drop glass trailers with fixed axles and nobody in the company ever got ticketed in CA with those same kind of trailers that I know of.

    Correct. CA has a KPRA regulation for trailers over 48ft. It’s technically not a bridge law because it has nothing to do with weight. It used to be for all trailers regardless of length, I think it was early 2000’s when they made it for trailers over 48ft.

    It’s called a kingpin law. State law. Bridge law is federal, hard to violate since we got rid of 40’ trailers.
