Tire Eater

[Mrparis]

Bought my 2018 civic Si coupe black brand new augs of 2018... since then if i hit any type of pothole i blow out a tire... tonight I hit a landmine pothole and it wrecked the driver side tire... again 3 weeks ago pull a tire on a long drive.. so thats 3 tires down in 58k miles... side note question: I get whining from 1.2.4 gears is that normal? when should i change tranny fluid?

If you haven’t done a trans fluid change by now, i’d do it soon. I’ve decided to do it every 30k miles.

Maintenance minder built into the infotainment should tell you if it should be done as well.

ok so 58k and i should change tranny fluid? thanks for heads up... im coming from a 2008 scion xb which tranny fluid needed to be changed every 90k miles... car had zero electronics in it.. but studid reliable at 300k miles over 10 years.

You can go 50K between gear oil changes...it's not as sensitive as a auto tranny.

What tires are you using? I haven't had any of those problems.

What tire pressure were you running at the time and when was the last time you checked them (Yesterday mine were down 4 psi due to the cold weather)? Our only tire-killer happened at 70 mph on I-81 at a bridge "pothole". It also cracked the wheel but both held air for another month before it was changed.

using goodyear tires ... i live in pothole city.... now mine you these potholes was like hitting a land mine... my head hit the ceiling when i hit them... car is small so potholes do damage

Compared to your old xB, he Si has thinner tire sidewalls (3.7" vs. 4.4") and a stiffer suspension. Both of which mean the Si won't stand up to potholes as well as the xB. Try to be careful where you can. Here's the difference in sidewall height.

Dang, where do you live?

Here, roads that are near industrial areas tend to have beat up roads, from the rigs I'm assuming. I'm able to avoid those roads and always think of the CTR stories of tires/rims getting beat up.

Factory Honda MTF should be changed annually or 20K miles at the most. Amsoil MTF goes a bit longer, you may get 2 yrs out of it... I've done this through 4 generations of Civics.

Honda MTF is pretty amazing IF you change out annually. Amsoil is very slightly better in the heat. I haven't tried GM Synchromesh (w/ friction modifier)... looks like it is not available in Canada... internet to the rescue!

As for the potholes... I would avoid them at all cost (save my life). The Si is not good off-roading...

thanks for this chart.... yes the box scion xb was killer in rain and snow.. i never had to dig it out i just warmed it up put in drive and ripped thru the snow... car was unreal reliable.. i love the SI.. just learning its flaws at this point... potholes are a big deal if you hit them fast enough in small car... i thought about a miata and thought if i hit the same pot hole in a miata i be dead lol... merry xmas !

Manual gear oil is typically changed out sooner than automatics and their fluids.
