CX-5 2019 2.5T Towing sub-1000 lbs, aftermarket tires...Thoughts?

[Catch22]

Hi Guys,

Wanted to know everyone’s thoughts about the following scenario:

2019 Cx5 2.5T (non-diesel)
Aftermarket wheel/tire setup: 235/60r18 +32 offset
Combined weight of trailer (no brakes) and motorcycle = approx 800 lbs

Traveling from Portland to Southern California in Summer temps. Am concerned about towing through elevations reaching 4310 ft. (Ie Siskiyou Summit)

Considering the wider-than-stock tires and weight of towed items, Thoughts? Thanks in advance!

Are you going to the top of Mt. Shasta or just traveling through on I-5? If just passing by, the Siskiyou Summit near CA/OR border is the highest point on I-5 and is only about 4,300 feet.

Thats correct just traveling on I5. Good call, edited

I wouldn't be worried. Towing 800 lbs (unbraked) should be okay (you could put 800 lbs of people and stuff inside the car with no problem).

Take your time. Leave more space out in front of you. Use manual mode on downgrades to drop down a gear or two to increase engine braking. Plan on less range since you'll be burning more gas towing. The 2.5T has ample power for going up hill and acceleration.

You may want to edit the title of this thread. It's not descriptive of what you're asking at all.

I’d put higher tire pressure than 35 psi which Mazda recommended in the US. You have full load, and putting 38 psi front and 42 psi rear would be what I do. Of course check the maximum tire pressure rating on the sidewall of your tires. Most likely it’s 51 psi. Here are tire pressure recommendations from EU Mazda CX-5 for your reference.
