Hey all
I recently went to some 18x12 -24 moto metals with mt Baja Mtz tires and they are measuring out at around 32” from my stock wheels with 265s on my 2016 5.3 6sp cc 3.42gear
Mpg went from 21 to 13 avg
trans temp up from 188 to 194 constant on highway
power feels like my old 4.8 now
I got a hypertech 2.0 tuner but no help really
I expected possibly a loss of 2-3mpg but this is a little much
I had planned to go 6” with 35s but there’s no way now unless these Mickey Thompson’s are causing way to much rolling resistance has anyone else had this big of a lose with mud tires or offset rims ?
