What 3630 and 3645 means, i already know, but wich is the softer/harder tire?
What do you guys recomend? I already tried som ZEN F 35Shore and rear 30, and i am looking for something harder.
Are these numbers (84...) new ones? Are there a the moment also other tires form Tamiya available?
Thanks for a answer in advance, greetings from Austria.
My recent collection of Tamiya tires and their "cards" tells me that 3645 = Rear and 3630 = Front tires. OK, duh.
Now, after having SOME of them side by side and running them:
84094 F103 Sponge Tyres C (3630, Front)= soft
84095 F103 Sponge Tyres C (3645, Rear) = soft
84096 F 103 HBR Medium Sponge Tires C (3630, Front) = firm
84097 F103 HBR Medium Sponge Tires C (3645, Rear) = firm
All the 84... series, 5 digit numbers are newer numbers.
These are updates to the older 53... series 5 digit numbers and can get confusing cuz the compounds are SIMILAR but not quite the same even though they have the same names.
Here goes, at least from what I have gathered in my collection.
53128 F-1 Front 3630 HBR Medium Sponge Tires = firm (more firm than the above 84096 although they are both described as HBR Medium)
53135 F-1 Rear 3645 HBR Medium Sponge Tires = firm
53129 F-1 Rear 3645 HBR Soft Sponge Tires = soft (not a supersoft tho)
I don't know the number for the Soft front tires cuz I never needed soft fronts.
I have only compared the old number Front HBR Mediums with the new number Front HBR Mediums and the old number is firmer with less steering.
For Rears the softest by far are the 84095 tires (above) or the 54136 Pre-Assembled wheel/tire combo. I feel they are the same compound, they work the same for me. Both still available.
They also FEEL the same as the older "Super Soft" tires.
I have all of these.
Those tires give as much rear traction as any Tamiya tire I have been able to find out about.
Pre-Assembled or Premounts are pricey but come mounted and trued on their wheels and they work but, again, they are super soft and will wear out quickly. You pay for traction!
For normal situations run them in matching sets front and rear.
For instance, Premounts front and rear are as much hook up as you can get, softer and tons of traction for low traction smooth asphalt.
The cheaper way to get this is to get the 84095 rear and the 84094 front tires and mount them yourself if you have wheels you can use. If you need wheels anyway, just get the premounts.
Again, a matching set and dialed combo.
Tamiya, in my opinion, matches their sets very well.
If you still have oversteering problems and want the firmest fronts, I think the old number 53128 HBR Mediums are the firmest but the 84096 HBR Mediums are more readily available and close to the same.
I say all this but still haven't found my great setup to get away from being loose where I run my F1 but I have settled on:
53128 Med fronts (firmest) and 84095 rears (softest).
Still searchin tho.
