Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

From Reddit, forums and review threads. Not part of our score
The community largely views the General AltiMAX RT45 as an exceptional value and a worthy successor to the RT43, frequently praising its quiet ride, comfort, tread life, and strong wet performance for the price. While many view it as a compelling mid-range alternative to premium options like the Michelin Defender 2, some users note trade-offs in steering responsiveness, soft sidewalls, or limitations in severe winter conditions compared to dedicated all-weather tires.
“I have a '23 Onyx Limited with Altimax RT45s (great wheels for the price!) and can confirm they fit if your Premium has the 20" wheels. If you have 18" wheels it doesn't look like the RT45s are an option at least when I search up tires on TireRack.”
“Need tires at a decent price general rt45 75,000 warreny T tires Paid 765 at walmart , T tires are soft and it makes my 80k hybrid van suspension feel brand new Also general made by Continental tires I'm sure Michelin is better but you're also going to pay like 400 more. Our vans come with H Tires the last set of tires I got were V Tires which are racing tires I didn't know about H,V or T tires Now that I got t tire from v it's a world of difference such a beautiful ride over all bumps and today I drove in the rain like nothing can't wait for the one too as my Goodyear tires weren't the best and that's giving them extra credit Read more”

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
