Comments from the Referee(s) and/or Editor:

Reviewer #1: There have been many papers presented during last few years about estimation of the tire friction based on the fact that aligning torque reaches the maximum with lower side slip angles than side force.
In my eyes I do not see anything new in this paper.
Besides that there are many quality issues which I comment for the purpose of feedback to the authors thinking about their future work.
The used language needs improvement and checking.
There should be a list and description of used notation.
The use of notation is heterogeneous. There are character used which are not explained like Theta y in explanation for equation 1 and 2. Sometimes the same letter is used for different meaning like alfa, which usually is used for side slip angle but in equation 23 for the longitudinal slope angle of the road.
The use of terminology is also varying. Sometimes for instance is talked about aligning torque sometimes of aligning moment. The use should be the same through whole document
The term friction coefficient is difficult. In estimation there should also be distinguished the friction used (typically low during normal driving) and friction available (how much could be used when driving on limits in recent tire and surface conditions)
For the paper, presenting also MFTM simulation results in fig. 2 and 3, does not bring any added value. Although they show, that you have capability to measure them.
The caster trail is assumed to be constant. I practice it is a function of suspension vertical position
In most of the vehicles the steering gear ratios are not constant
It is assumed that the steering torque could be measured by EPS system. Is there any indication that he accuracy would be sufficient. Especially while using small steering angles
The used vehicle model is unconventional in this kind of use. Typically the model does not have roll degree of freedom. It is assumed that he effect of the roll is low enough.
In the used model equation 5 is not correct. The rolling does not have any effect on the sum of the lateral forces like is presented. There are also mistakes in equation 7
Like the author notices the problem is availability of the estimation in MAMM only after the maximum value of the aligning torque is reached. In real driving situations also the friction is often changing rapidly.
I have not checked the validity of equations 8 .. 13
Assumption that the tire slip is less than 5 degrees is not valid. Same kind of assumption is also presented later saying that on low friction road the steering angle is smaller than usual. Based on my experience on slippery winter roads the angle often tends to be much larger. The reason is that with under steering phenomena more steering angle is needed to develop the necessary turning forces with low friction available. With over steering vehicle the situation is different but even in these cases the angle can be high but sometimes to the opposite direction
In the calculations of the wheel load distribution there is not separated the driving speed and the relative sped as related to the air (effect of wind)in aerodynamic force portion
In equations 25 and 26 the handling of unsuspended mass is not correct. It is assumed that the height of CC of this mass is the same as roll center height which is not true.
In table 2 what means the value on last row. Notation not explained and in equations two different ratios.
It is told that a look up table has been constructed but there is no example of its content shown.
In the simulation first is explained results from ramp steer. Then suddenly the results in fig 11 look like sinusoidal or pylon type
The test behind fig 11 should be described
For the pylon tests some results from instrumented vehicle are shown.  Obviously they are connected to the results in fig. 14. But there I no indication for instance what torque information is used for the estimations. Is the torque applied by driver measured by the force steering wheel seen in fig. 12 or is it from EPS system. Etc. Are the results based on realtime estimation
In conclusion is mentioned that it is hard to reach accuracy and computational speed at same time. However, there are no facts about these shown anywhere in the paper. What kind of accuracies and what kind of calculation speed can be achieved.
The list of references could have had more coverage for the recently published papers on the field.




Reviewer #2: The manuscript presents interesting approaches to tyre-road friction estimation. The background and the methodology are clearly presented. However, the results presented in Sections 3.3, 3.4 and 4 are disappointing because they lack details, analyses and discussions. Maybe  the authors tried to cover quite a large area with the results but at the price of relatively limited depth. I would recommend the manuscript for publication only if the authors improve and extend considerably the results sections of the paper, by providing more details, analyses of results and discussions.

Specific comments:

1) Section 2: state which coordinate systems do you use for the vehicle models and the tyre models.

2) 'l' appears only in Eq. (9) but is referred to after Eqs. (1) and (2).

3) Section 2.1.2: which MFTM do you use?

4) Important: please provide the tyre parameters that you use. Fig. 3 has little meaning without parameter values.

5) Fig. 4: specify the direction of motion.

6) Section 2.3: state that the longitudinal velocity is constant.

7) How do you obtain the results in Figure 5?

8) The discussion in Section 3.3 before Table 2 is not clear.

9) Describe in the text what is shown in Fig. 9.

10) Important: the conditions of the experiments are not given in the paper.

11) All authors names should appear in the References.
